New transistor’s superlative properties could have broad electronics applications

New Post has been published on https://thedigitalinsider.com/new-transistors-superlative-properties-could-have-broad-electronics-applications/

New transistor’s superlative properties could have broad electronics applications

In 2021, a team led by MIT physicists reported creating a new ultrathin ferroelectric material, or one where positive and negative charges separate into different layers. At the time they noted the material’s potential for applications in computer memory and much more. Now the same core team and colleagues — including two from the lab next door — have built a transistor with that material and shown that its properties are so useful that it could change the world of electronics.

Although the team’s results are based on a single transistor in the lab, “in several aspects its properties already meet or exceed industry standards” for the ferroelectric transistors produced today, says Pablo Jarillo-Herrero, the Cecil and Ida Green Professor of Physics, who led the work with professor of physics Raymond Ashoori. Both are also affiliated with the Materials Research Laboratory.

“In my lab we primarily do fundamental physics. This is one of the first, and perhaps most dramatic, examples of how very basic science has led to something that could have a major impact on applications,” Jarillo-Herrero says.

Says Ashoori, “When I think of my whole career in physics, this is the work that I think 10 to 20 years from now could change the world.”

Among the new transistor’s superlative properties:

It can switch between positive and negative charges — essentially the ones and zeros of digital information — at very high speeds, on nanosecond time scales. (A nanosecond is a billionth of a second.)

It is extremely tough. After 100 billion switches it still worked with no signs of degradation.

The material behind the magic is only billionths of a meter thick, one of the thinnest of its kind in the world. That, in turn, could allow for much denser computer memory storage. It could also lead to much more energy-efficient transistors because the voltage required for switching scales with material thickness. (Ultrathin equals ultralow voltages.)

The work is reported in a recent issue of Science. The co-first authors of the paper are Kenji Yasuda, now an assistant professor at Cornell University, and Evan Zalys-Geller, now at Atom Computing. Additional authors are Xirui Wang, an MIT graduate student in physics; Daniel Bennett and Efthimios Kaxiras of Harvard University; Suraj S. Cheema, an assistant professor in MIT’s Department of Electrical Engineering and Computer Science and an affiliate of the Research Laboratory of Electronics; and Kenji Watanabe and Takashi Taniguchi of the National Institute for Materials Science in Japan.

What they did

In a ferroelectric material, positive and negative charges spontaneously head to different sides, or poles. Upon the application of an external electric field, those charges switch sides, reversing the polarization. Switching the polarization can be used to encode digital information, and that information will be nonvolatile, or stable over time. It won’t change unless an electric field is applied. For a ferroelectric to have broad application to electronics, all of this needs to happen at room temperature.

The new ferroelectric material reported in Science in 2021 is based on atomically thin sheets of boron nitride that are stacked parallel to each other, a configuration that doesn’t exist in nature. In bulk boron nitride, the individual layers of boron nitride are instead rotated by 180 degrees.

It turns out that when an electric field is applied to this parallel stacked configuration, one layer of the new boron nitride material slides over the other, slightly changing the positions of the boron and nitrogen atoms. For example, imagine that each of your hands is composed of only one layer of cells. The new phenomenon is akin to pressing your hands together then slightly shifting one above the other.

“So the miracle is that by sliding the two layers a few angstroms, you end up with radically different electronics,” says Ashoori. The diameter of an atom is about 1 angstrom.

Another miracle: “nothing wears out in the sliding,” Ashoori continues. That’s why the new transistor could be switched 100 billion times without degrading. Compare that to the memory in a flash drive made with conventional materials. “Each time you write and erase a flash memory, you get some degradation,” says Ashoori. “Over time, it wears out, which means that you have to use some very sophisticated methods for distributing where you’re reading and writing on the chip.” The new material could make those steps obsolete.

A collaborative effort

Yasuda, the co-first author of the current Science paper, applauds the collaborations involved in the work. Among them, “we [Jarillo-Herrero’s team] made the material and, together with Ray [Ashoori] and [co-first author] Evan [Zalys-Geller], we measured its characteristics in detail. That was very exciting.” Says Ashoori, “many of the techniques in my lab just naturally applied to work that was going on in the lab next door. It’s been a lot of fun.”

Ashoori notes that “there’s a lot of interesting physics behind this” that could be explored. For example, “if you think about the two layers sliding past each other, where does that sliding start?” In addition, says Yasuda, could the ferroelectricity be triggered with something other than electricity, like an optical pulse? And is there a fundamental limit to the amount of switches the material can make?

Challenges remain. For example, the current way of producing the new ferroelectrics is difficult and not conducive to mass manufacturing. “We made a single transistor as a demonstration. If people could grow these materials on the wafer scale, we could create many, many more,” says Yasuda. He notes that different groups are already working to that end.

Concludes Ashoori, “There are a few problems. But if you solve them, this material fits in so many ways into potential future electronics. It’s very exciting.”

This work was supported by the U.S. Army Research Office, the MIT/Microsystems Technology Laboratories Samsung Semiconductor Research Fund, the U.S. National Science Foundation, the Gordon and Betty Moore Foundation, the Ramon Areces Foundation, the Basic Energy Sciences program of the U.S. Department of Energy, the Japan Society for the Promotion of Science, and the Ministry of Education, Culture, Sports, Science and Technology (MEXT) of Japan.

Why do headlights dim when a car engine is turned on?

Headlights dimming when you start the car’s engine is usually normal, but it can also signal an underlying electrical issue. Here’s why it happens and when to be concerned:

1. Normal Behavior: Momentary Dimming During Engine Startup

Cause: When you turn the key (or push the start button), the starter motor draws a massive surge of power (150–300+ amps) from the battery. This temporarily drops the battery voltage (from ~12.6V to 9–10V), reducing power to the headlights.

Duration: Dimming lasts 1–2 seconds while the engine cranks. Lights should brighten once the alternator begins charging (~14V).

Typical in: Older vehicles, cars with weaker batteries, or halogen headlights (LEDs are less affected due to lower power draw).

2. Abnormal Dimming: Persistent or Severe Voltage Drop If headlights stay dim after the engine starts or dim while driving, it indicates a problem:

Common Causes

Weak or Failing Battery: • A degraded battery can’t maintain voltage under load. • Test: Check battery voltage (engine off: <12.4V = weak; running: <13.5V = alternator issue).

Faulty Alternator: • Worn brushes, bad diodes, or a loose belt reduce charging capacity. • Symptom: Lights dim when using accessories (AC, heated seats).

Corroded or Loose Connections: • Corrosion on battery terminals, ground straps, or headlight wiring increases resistance, causing voltage drop.

Overloaded Electrical System: • Aftermarket upgrades (amplifiers, light bars) strain the alternator.

3. How to Diagnose

Test the Battery: • Use a multimeter to check voltage (engine off: 12.6V ideal; engine running: 13.5–14.5V). • Load-test the battery at an auto parts store.

Inspect the Alternator: • Rev the engine to 2,000 RPM while monitoring voltage (should stay steady at ~14V).

Check Wiring: • Clean battery terminals with baking soda/water and a wire brush. • Trace ground connections (engine block to chassis) for corrosion.

Reduce Load: • Disconnect aftermarket electronics to see if dimming stops.

4. Solutions

Replace the Battery: Opt for a higher CCA (Cold Cranking Amps) rating if you live in a cold climate.

Repair/Replace Alternator: Rebuild or upgrade to a high-output alternator if needed.

Upgrade Wiring: Replace corroded cables or install a headlight relay harness to reduce voltage drop.

Switch to LEDs: LED bulbs draw less power and are less affected by voltage fluctuations.

When to Worry

Lights stay dim even after the engine starts.

Flickering or random brightness changes while driving.

Battery warning light appears on the dashboard.

Cost Estimates Fix Cost Range Battery replacement $100–$300 Alternator repair/replace $200–$600 Wiring harness upgrade $50–$150 (DIY) LED bulb conversion $40–$200

Key Takeaway: Brief dimming during startup is normal, but persistent dimming means your electrical system needs attention. Address issues early to avoid being stranded with a dead battery! 🔧🔋

EP-5 Electra thoughts

-human name would be Jet McGinnis (blatant reference to the EP-5’s nickname and paint scheme origin)

-fun but depressing dumpster fire rockstar, spends extravagantly with money he doesn’t have and constantly fighting with his record label

-AC vs DC mode is a VERY distinct change in personality. In AC he’s wild and hot headed and prone to mood swings and impulsive decisions, often becoming self-destructive, but also at his most creative and vibrant. Lots of raising/flailing his arms to reflect use of overhead power. Mania is a pretty fair descriptor. In DC mode he’s much calmer but downright lethargic. Skates in “sticky feet” style to represent electrical pickup from below. This is all based on the EP-5s being built for rapid acceleration and having problematic early rectifiers for AC operation, with DC mode being a lower voltage (and power) way to get through specific tunnels with third rail.

-virtuoso with almost any kind of string instrument, constantly experimenting with and collecting them. Tries to make electric versions of them with… questionable success

-obsessed with tube-based audio tech, like amps, organs, etc. In reference to the EP-5s similarly being defined by pre-solid state tech (and the issues it has in trains). Loves the idea of “playing the studio” but too impatient to stand the recording process, much more into performing live or jamming

-revolving door of band members because he’s terrible at communication and so erratic and hard to work with. MAJOR issue for the EP-5s, they couldn’t link up with other engines to “work together” which limited their use.

-banned from several places for being a borderline pyromaniac. Loves blowing up electronics, setting things on fire, and setting off pyrotechnics indoors.

-I’m split on whether he accurately has a Hancock Air Whistle or has the inaccurate horn many toys did. Both are funny troll moves in their own ways.

-Can be very fun to hang out with in the short term if unbearable long-term. He’ll just go on and on about music and gear and esoteric stuff about wires and vibrations and constantly gets into fun but regrettable shenanigens

-has very mixed opinions on the Beatles. How dare they kill surf rock and drive his fellow tube technology-obsessed New Englander, Dick Dale, into obscurity. But also the psychedelic stuff is fun

-feel free to borrow him if desired. Most stuff I make here is open to take and use unless stated otherwise

Hey, you!

This is the official blog for Mauville Fix Shop, the city's BEST electronics repair store for Pokédex devices, PokeNavs, Pokégears, Pokétches, and other devices! If you're in need of a fix for your tech, head on over to our store at 310 Violet Street today!

...

OK, now that my manager is satisfied with the draft, I can work on the actual post! I'm Nick Docomo (he/him), age 19.

I'm the designated account manager for Mauville Fix Shop's Tumblr blog since I'm already on here... a little bit much. Moving along, I also work on old-model Pokénav repairs part-time. Primarily, though, I'm a student at Mauville Technical College majoring in electrical engineering!

To top off my resume, I'm training to be the next Mauville gym leader under Swell Shock Wattson (look, he set that as his Trainer's Eyes title and I've gotta roll with it). My team right now is:

Day (♂) the Heliolisk: My starter and current strongest team member, Day is an incredible attacker when the sun's up! Very friendly out of battle, too.

Bhaskara the Heat Rotom: It would watch the world burn just out of curiosity of what happens after. I respect its commitment to science regardless. After being given a smart oven from Wattson (who incorrectly predicted it would talk), Wattson gifted it to me.

Amp (♀) the Raichu: I caught her as a Pikachu 2 years ago on a field trip to the Safari Zone. She's a crafty little Pokémon, which is sometimes good for me but not when she pranks me, the team, or anyone else really.

Ohm (♀) the Flaaffy: An old man working at the Day Care on Route 117 just gave me an egg 4 years ago and Ohm was the Mareep that ended up hatching. She's on the sterner side of things, but not hostile.

Jet (♀) the Fletchling: I noticed that as a Fire type specialist I have a lot of Electric types so I searched for a member of the Fletchling to tip the scales back to Fire. I caught Jet very recently, but her battle-hunger’s already on full display, especially when she wants to battle Day.

Other facts about me:

I'm 5'8", have black hair and brown eyes, and slightly tan skin.

I'm nearsighted as the planet is large. I don't like it, but it's not too bad when I have my glasses.

Screw Macro Cosmos, I support the right to repair!

I'm a member of my college's second-best trivia team as well as the college's best Voltorb Flip player!

Mauville Fix Shop has been offering free 1-year warranty on all Pokédexes repaired for students at our shop! (See I'm promoting the store, can't fire me for THAT!)

OOC: Hi, @punjab-official here on my debut Rotomblr blog! My pronouns are he/him (although any are fine), and I'm an adult. Like I said in the blog description, I will NOT be tagging for unreality, so here's another notice. If there's anything I missed that you need me to clarify, just send an ask or message!

This blog is fairly canon-flexible in that Nick will be able to interact with many other blogs’ canons, but Nick generally isn’t aware of whenever a person is a canon-outsider (in terms of Nick’s universe). About Nick’s own canon, the awakening of Primal Groudon and Kyogre hasn’t happened yet, and as such Nick may not take Teams Aqua and Magma seriously or be open to accepting them.

Whenever Nick says he’s a Fire type specialist, it’s for a type-specialty swap for Muse Mixup Madness (he usually considers himself an Electric type specialist).

I’m generally accepting of Pelipper mail, but on days that’s not the case I’ll post so here. In-character reblogs will be tagged as “ic reblog” and/or “nick reblogs”, and posts that will be relevant for a later story/post or will reveal an important aspect of Nick’s character will be tagged as “blog development”. “nick’s answers” will be for in-character answered asks.

And I have never once used the wrong blog. Ever. Totally not.

What is Electricity?

[The following is a rough script for a student-led presentation to my HVAC classmates, who are currently building and testing basic AC circuits with no formal introduction to the fundamental concepts of electricity and energy. Like, line voltage. I wish I was joking.]

Electricity is all around us. It charges our phones, amplifies our voices, heats our homes, and allows us to communicate from vast distances. It is humanity's greatest discovery. Greater than fire, greater than the internal combustion engine. Greater than nuclear fission. Nothing in this room would exist without it.

For almost two weeks, now, we have been building circuits for electricity to pass through and do work for us. But do you know what this invisible force even is? Today, we are going to change that.

We will start small, at the atomic level. This is the basic atomic model you may have seen before. We have a nucleus, made of neutron and proton particles, and orbitals around the nucleus occupied by electron particles. The neutron has a neutral charge, the proton has a positive charge, and the electron has a negative charge.

This is the atomic model for copper, the most common conductor used in electrical circuits. It is a kind of metal. We use copper over other conductive metals because it is inexpensive and is good enough for general use. Copper conducts electricity so well because of this guy. The valence electron. The valence shell is the outermost orbital of any given atom, and in copper, there is just one.

The fewer valence electrons there are, the more conductive an element is [simplification, necessary]. There can be up to eight electrons in an atom's valence shell [simplification].

This is a copper wire. There are two kinds: solid core and stranded core. When the wire isn't connected to anything, those valence electrons are idle, remaining with their respective atoms [simplification]. But when we apply a voltage across the wire, those electrons are moved from negative to positive along the wire simultaneously. This movement of electrons is what we call current, and is measured in amperage, or amps, symbolized by "I".

Let's step back for a moment. I mentioned voltage, but what exactly is it? Voltage is the difference in electrostatic potential energy between two points [simplification]. Voltage can be produced by chemicals and plates in a battery, or can be produced by a generator. I will go into detail on generators later. For now, let us examine a battery.

The standard battery in your car is a 12v lead-acid battery. The voltage between the positive and negative terminals is 12.6v in a healthy battery. Inside the battery are lead plates connected like so, and immersed in an acidic liquid we call electrolyte. There are 6 cells in this battery, and each has an individual voltage of 2.1v. Together in series, they produce 12.6v across the terminals. When we charge the battery, all we are doing is moving electrons from one side of the battery to the other with an external circuit. When the battery is charged, we will have a collection of negatively charged atoms on the negative plates, and positively charged plates on the positive plates.

[Sidebar: When an atom looses an electron, it becomes a positive ion, because the total charge balance between the protons and electrons has been skewed so that there are more protons than there are electrons. The opposite is true when an atom takes on an electron; it becomes a negative ion.]

The electrons of the negative ions are compelled to move over to fill the vacancy of the positive ions. This compulsion is our voltage. It's a potency of opposing ions in this battery.

When we complete a circuit, such as this one, we provide a path from those electrons to move and equalize the potential difference. When they recombine with the positive ions on the positive side, the battery loses voltage; the potential is reduced and the battery will be depleted. This is why your phones and your cars need to be charged regularly; to reset this potential.

What I just described is a DC, or direct-current, circuit. The electrons moved in only one direction. But we have been building AC circuits. What is an AC circuit? AC stands for alternating-current. AC will reverse the direction of electron flow periodically, and this rate of this change in flow direction is called frequency. In the US, our outlets output 60hz (hz, or Hertz, is the unit of frequency), or 60 direction changes per second. This is how we represent AC on a graph. This is the wave model. If we measure a wave like this, we can calculate its frequency by the time between the two nearest positive zero-crossings. It could be any point on the wave, in truth, so long as they are the same.

If we could see the electrons moving in the wire, we would see them move in one direction before slowing down and then moving in the other direction, like a train. [simplification, we really don't need to get into transmission line theory or wave theory].

How do we produce AC? We don't get it from a battery, but it's available at any given outlet in this room. To answer this, we will have to explore the fascinating realm of electromagnetism.

A magnet, like this one, is what we call a permanent magnet. It is iron that has been polarized through exposure to an magnetic field. If I place it on this steel frame, we see that it sticks to it when it gets close enough. This is possible because iron, cobalt, and nickel are elements that are magnetically permeable. Aluminum is not, for example, and cannot be influenced by magnetism. This property-based magnetism is what we call ferromagnetism. It's not important to know that term, though [perhaps cut this part out].

So, we can magnetize iron, but how was that accomplished? Through electromagnetism. This is a wire, just like I showed you before. When we apply a voltage across it and current flows, something else happens: a small magnetic field is generated perpendicular to the flow of the electrons in the wire. The direction of this field depends on the direction of current flow. The direction doesn't matter for this demonstration, but know that it can change.

This small field is useless to us in its current state, but if we coil the wire around in close proximity, such at this, those small fields combine to create a larger, more powerful magnetic field. What we've just created is an electromagnet. We have turned electrostatic potential energy into magnetic potential energy. This field can do many different things for us, and we will explore them in the next lecture about circuit components.

There is a reverse side of electromagnetism, though. If we pass a magnetic field, either from a permanent magnet or an electromagnet coil, over a wire, a current is induced in the wire. The passing of the magnetic field over the wire causes electrons to move in the wire. Again, in this current configuration, the effect is relatively weak. If we want to extract more current from this effect, we need to coil the wire. Now, we have more of the wire being exposed to the field at once, and this induces a stronger voltage and current in the wire [simplification].

"magnetism is seen whenever electrically charged particles are in motion—for example, from movement of electrons in an electric current, or in certain cases from the orbital motion of electrons around an atom's nucleus."

This means that electricity and magnetism are always present, together. We cannot have current flow with magnetic field generation, and vice versa. To dig any deeper into it is the realm of physics. But magnetism is not magic, it is an understood property of particles in motion.

So, stepping back, how do we get AC electricity? This is the job of powerplants. Have any of you heard the phrase "energy cannot be created nor destroyed"? Its meaning is literal. I cannot summon energy from nothing. Energy exists in many states and is always being converted between them. There is kinetic energy, which is the movement of atoms; this includes temperature--heat--and my arm moving to throw this marker.

There is gravitational potential energy (GPE), which results from the force of gravity. If I stand on a beach, I have a certain GPE. If I stand on the top of a cliff over the beach, I have more GPE than if I were down on the beach. Just like EsPE, I am the electron on the negatively charged battery plate, and the beach down below is the positive plate. The circuit is the air and all the trees and rocks I hit on the long fall down.

There is chemical potential energy (CPE), this is the energy that is stored in the bonds in, and between, elements. Calories is the unit of CPE in food, for example. It is the amount of energy stored in the food we eat.

There is elastic potential energy (ElPE), which is the energy stored in a spring or your tendons, for example, when stretched or compressed.

There is magnetic potential energy (MPE), which is the energy stored is magnetic fields.

There is electrostatic potential energy (EsPE), which we just covered.

And lastly, there is nuclear potential energy (NPE) which is the energy in the bonds between the particles in the nucleus of the atom.

All this energy potential can be used to perform work; it can be converted to kinetic energy through machinery. In Puget Sound, we get most of out energy from natural gas powerplants and hydroelectic dams. To the east, there are large wind and solar farms, and to the south, there is a single coal powerplant.

But these are just the names for the buildings. What's happening inside them that gives us this power? Let us use the hydroelectric powerplant as our first example. A dam is a structure that obstructs the flow of water in a river to create a reservoir. The reservoir water has a higher GPE than the outflowing water, and is compelled to fall to reach a lower energy state. To convert that GPE to EsPE, we need some kind of machine. This is the job of the generator and turbine. The water is piped down into a turbine, which has dozens or hundreds of blades that the falling water turns. The blades rotate a shaft, which is attached to a magnet. This magnet spins around coils of wire arranged like so. This is why you see power lines in sets of three; they are the output of a generator like this.

After the water passes through the turbine, it is then exhausted to the river below, having provided as much energy conversion as we could extract. So, we took GPE in the water, converted it to kinetic energy with the turbine, and then turned the kinetic energy to EsPE with the spinning magnet. Isn't that fascinating?

Let's look at a natural gas plant. We take methane, CPE, burn it, which converts the CPE to kinetic energy, so that it boils water to create steam. This is still kinetic energy. Latent heat. Then, we pipe that steam through a turbine to do the exact same thing as the hydropower plant: to spin a magnet over coils of wire. The coal plant works exactly the same. The high pressure generated from the boiling of water is compelled to flow to a low-pressure area; the exhaust to the outside, somewhere. And on its way, we have it spin a turbine.

In fact, a nuclear powerplant does the same thing, as well. Through fission reaction, NPE is converted to kinetic energy as heat to boil water, rinse and repeat.

Okay, let's look at solar. Solar power introduces some nuance into our energy model because sunlight is an electomagentic wave. It's a compound form of energy that is both electrostatic and magnetic. Specifically, we are harnessing the EMPE in a particle called the photon. The photon strikes the solar panel, which is made up of photovoltaic cells, and its energy is given up to the circuit inside. The insides of a solar panel are too complex for this lecture, but that photon's energy gets converted to EsPE. But unlike the turbine generators previously described, the current is DC, not AC. To turn DC to AC, we must first pass it through an inverter. Not going to describe how it works here, but know that it converts DC to AC for use on the grid.

Lastly, let us look at wind. Kinetic energy in the air as wind is used to rotate the turbine which are the windmill blades. The blades are connected to a shaft which is connected to a magnet which rotates around three packs of coiled wire (there is a gearbox in there as well, but that's not necessary to describe). Boom! Three-phase AC power from the sky.

As you can see, there are many ways to produce AC. Through other electrical infrastructure, such as transmission towers and substations, the AC power makes it wherever it is needed, including this classroom. All by harnessing energy in its various forms.

This concludes our introduction to electricity. I hope you will join me later for the introduction to schematics and circuit components; the devices that allow us to harness electricity to perform work.

Any questions?

Taming the Current: The Underrated Power of the Thyristor Rectifier

In a world driven by electricity, few components hold as much unseen power as the thyristor rectifier. It doesn’t get headlines like electric vehicles or smart grids, but quietly, behind the scenes, it helps drive them both—and so much more.

If you’re someone who’s never thought deeply about how high-power AC gets tamed into usable DC, buckle up. We’re diving deep into the heart of industrial power electronics with an angle that’s not just about volts and amps—but about control, evolution, and quiet efficiency.

The Quiet Transformer: What Is a Thyristor Rectifier?

Let’s start at the beginning, but skip the dry textbook definitions. Think of a thyristor rectifier as a high-powered traffic cop for electricity. Its job? Converting alternating current (AC), which flows back and forth, into direct current (DC), which flows in one direction—reliably and efficiently.

At its core is the thyristor, a type of semiconductor device that acts like a controllable switch. Unlike traditional diodes, which simply allow current to pass when forward-biased, thyristors can be precisely controlled—turned on at specific points in the AC cycle for variable output.

In short, where an ordinary rectifier is a gate, a thyristor rectifier is a smart gatekeeper.

Why It Matters: The Human Side of Heavy Current

Imagine a steel plant operating massive furnaces, or a subway system with regenerative braking. These systems don’t just need DC—they need controllable, adaptable, and efficient DC. And downtime isn’t just inconvenient, it’s expensive and potentially dangerous.

That’s where the thyristor rectifier makes all the difference.

Because it can manage the timing of conduction, it allows engineers to regulate output voltage and current with surgical precision. This leads to:

Energy savings through improved efficiency,

Longer equipment life due to smoother power transitions,

Increased safety via real-time response to load conditions.

If you’ve ever stepped into an industrial control room and felt that reassuring hum of everything working together—that’s the thyristor rectifier at work behind the panels.

Diving Deeper: Anatomy and Working Principles

Let’s crack one open—figuratively, of course.

A typical thyristor rectifier system includes:

Phase-controlled thyristors arranged in bridge or half-controlled configurations,

Snubber circuits to protect against voltage spikes,

Triggering circuits that precisely fire the thyristors,

Sometimes feedback and control loops to adjust output dynamically.

The beauty lies in its simplicity and scalability. Whether it’s a three-phase system delivering 500V or a megawatt-level DC source for electrolysis, the principles remain the same.

By delaying the firing angle of the thyristors—measured in degrees from the AC zero-crossing—engineers can fine-tune the amount of energy passed to the load. This ability to “chop” the waveform with intent makes thyristor rectifiers superior in heavy-duty applications compared to uncontrolled diode rectifiers.

Applications Beyond the Textbook

Where do these rectifiers shine? Let’s go beyond the usual bullet points.

1. Steel and Metallurgy

From electroplating to arc furnaces, the ability to precisely control current flow is critical. The thyristor rectifier enables adjustable outputs to match process demands, reducing energy waste and improving product quality.

2. Railway Electrification

DC motors are common in rail systems. These rectifiers power not just locomotives, but also charging stations, tunnel fans, and switching systems—all while ensuring resilience to voltage fluctuations.

3. HVDC Transmission

High-voltage DC lines often start and end with powerful thyristor converters. Their robustness in managing large voltages and currents makes them ideal for long-distance, low-loss electricity transport.

4. Industrial Battery Chargers

Large-scale UPS systems or EV fleets need reliable, programmable charging. Thyristor rectifiers adapt dynamically to battery conditions, extending battery life and minimizing charging time.

The Evolutionary Advantage: Why Thyristors Still Matter in the IGBT Era

It’s tempting to ask: “Aren’t newer technologies like IGBTs and MOSFETs replacing thyristors?”

The answer is nuanced.

In lower power and high-frequency applications, yes—IGBTs dominate. But when it comes to rugged, high-power, high-voltage use cases, the thyristor rectifier remains unmatched in:

Simplicity (fewer components = less failure),

Thermal resilience (can handle high current density),

Cost-effectiveness at scale.

It’s not a matter of old vs. new—it’s about choosing the right tool for the job. And in many cases, thyristors still wield the edge.

Challenges in Implementation: Not All Smooth Sailing

Every technology has its quirks, and the thyristor rectifier is no exception.

Harmonic distortion: Poorly controlled thyristors can inject undesirable harmonics into the power line.

Complex triggering: Requires precise gate control, especially in high-speed or multi-phase systems.

Size and cooling: High power = high heat. Adequate heat sinks and ventilation are non-negotiable.

Yet, modern control systems have addressed many of these hurdles. With DSP-based controllers, digital firing circuits, and active filtering, today’s rectifiers are smarter and cleaner than ever.

What the Future Holds: Smarter Rectification

As we move toward a more electrified, digitally managed future, the thyristor rectifier is evolving too.

We’re seeing:

Hybrid systems combining thyristors and IGBTs,

Remote diagnostics via IoT integration,

Real-time waveform shaping through AI-powered controllers.

Imagine a rectifier that not only powers your equipment but also sends you predictive maintenance alerts and efficiency reports. That’s where we’re headed—and thyristors are along for the ride.

Final Thoughts: Why You Should Pay Attention

The next time you pass by a humming transformer station, step inside a factory floor, or plug in an industrial EV charger, remember—there’s a high chance a thyristor rectifier is working silently in the background, keeping the currents flowing and the chaos at bay.

It’s not glamorous, and it doesn’t come with marketing hype. But it delivers something far more valuable: control, efficiency, and rock-solid dependability.

In a world chasing smart everything, maybe it’s time to appreciate the smart decisions that have already been made—like choosing the thyristor rectifier.

Elaine Liu: Charging ahead

New Post has been published on https://thedigitalinsider.com/elaine-liu-charging-ahead/

Elaine Liu: Charging ahead

MIT senior Elaine Siyu Liu doesn’t own an electric car, or any car. But she sees the impact of electric vehicles (EVs) and renewables on the grid as two pieces of an energy puzzle she wants to solve.

The U.S. Department of Energy reports that the number of public and private EV charging ports nearly doubled in the past three years, and many more are in the works. Users expect to plug in at their convenience, charge up, and drive away. But what if the grid can’t handle it?

Electricity demand, long stagnant in the United States, has spiked due to EVs, data centers that drive artificial intelligence, and industry. Grid planners forecast an increase of 2.6 percent to 4.7 percent in electricity demand over the next five years, according to data reported to federal regulators. Everyone from EV charging-station operators to utility-system operators needs help navigating a system in flux.

That’s where Liu’s work comes in.

Liu, who is studying mathematics and electrical engineering and computer science (EECS), is interested in distribution — how to get electricity from a centralized location to consumers. “I see power systems as a good venue for theoretical research as an application tool,” she says. “I’m interested in it because I’m familiar with the optimization and probability techniques used to map this level of problem.”

Liu grew up in Beijing, then after middle school moved with her parents to Canada and enrolled in a prep school in Oakville, Ontario, 30 miles outside Toronto.

Liu stumbled upon an opportunity to take part in a regional math competition and eventually started a math club, but at the time, the school’s culture surrounding math surprised her. Being exposed to what seemed to be some students’ aversion to math, she says, “I don’t think my feelings about math changed. I think my feelings about how people feel about math changed.”

Liu brought her passion for math to MIT. The summer after her sophomore year, she took on the first of the two Undergraduate Research Opportunity Program projects she completed with electric power system expert Marija Ilić, a joint adjunct professor in EECS and a senior research scientist at the MIT Laboratory for Information and Decision Systems.

Predicting the grid

Since 2022, with the help of funding from the MIT Energy Initiative (MITEI), Liu has been working with Ilić on identifying ways in which the grid is challenged.

One factor is the addition of renewables to the energy pipeline. A gap in wind or sun might cause a lag in power generation. If this lag occurs during peak demand, it could mean trouble for a grid already taxed by extreme weather and other unforeseen events.

If you think of the grid as a network of dozens of interconnected parts, once an element in the network fails — say, a tree downs a transmission line — the electricity that used to go through that line needs to be rerouted. This may overload other lines, creating what’s known as a cascade failure.

“This all happens really quickly and has very large downstream effects,” Liu says. “Millions of people will have instant blackouts.”

Even if the system can handle a single downed line, Liu notes that “the nuance is that there are now a lot of renewables, and renewables are less predictable. You can’t predict a gap in wind or sun. When such things happen, there’s suddenly not enough generation and too much demand. So the same kind of failure would happen, but on a larger and more uncontrollable scale.”

Renewables’ varying output has the added complication of causing voltage fluctuations. “We plug in our devices expecting a voltage of 110, but because of oscillations, you will never get exactly 110,” Liu says. “So even when you can deliver enough electricity, if you can’t deliver it at the specific voltage level that is required, that’s a problem.”

Liu and Ilić are building a model to predict how and when the grid might fail. Lacking access to privatized data, Liu runs her models with European industry data and test cases made available to universities. “I have a fake power grid that I run my experiments on,” she says. “You can take the same tool and run it on the real power grid.”

Liu’s model predicts cascade failures as they evolve. Supply from a wind generator, for example, might drop precipitously over the course of an hour. The model analyzes which substations and which households will be affected. “After we know we need to do something, this prediction tool can enable system operators to strategically intervene ahead of time,” Liu says.

Dictating price and power

Last year, Liu turned her attention to EVs, which provide a different kind of challenge than renewables.

In 2022, S&P Global reported that lawmakers argued that the U.S. Federal Energy Regulatory Commission’s (FERC) wholesale power rate structure was unfair for EV charging station operators.

In addition to operators paying by the kilowatt-hour, some also pay more for electricity during peak demand hours. Only a few EVs charging up during those hours could result in higher costs for the operator even if their overall energy use is low.

Anticipating how much power EVs will need is more complex than predicting energy needed for, say, heating and cooling. Unlike buildings, EVs move around, making it difficult to predict energy consumption at any given time. “If users don’t like the price at one charging station or how long the line is, they’ll go somewhere else,” Liu says. “Where to allocate EV chargers is a problem that a lot of people are dealing with right now.”

One approach would be for FERC to dictate to EV users when and where to charge and what price they’ll pay. To Liu, this isn’t an attractive option. “No one likes to be told what to do,” she says.

Liu is looking at optimizing a market-based solution that would be acceptable to top-level energy producers — wind and solar farms and nuclear plants — all the way down to the municipal aggregators that secure electricity at competitive rates and oversee distribution to the consumer.

Analyzing the location, movement, and behavior patterns of all the EVs driven daily in Boston and other major energy hubs, she notes, could help demand aggregators determine where to place EV chargers and how much to charge consumers, akin to Walmart deciding how much to mark up wholesale eggs in different markets.

Last year, Liu presented the work at MITEI’s annual research conference. This spring, Liu and Ilić are submitting a paper on the market optimization analysis to a journal of the Institute of Electrical and Electronics Engineers.

Liu has come to terms with her early introduction to attitudes toward STEM that struck her as markedly different from those in China. She says, “I think the (prep) school had a very strong ‘math is for nerds’ vibe, especially for girls. There was a ‘why are you giving yourself more work?’ kind of mentality. But over time, I just learned to disregard that.”

After graduation, Liu, the only undergraduate researcher in Ilić’s MIT Electric Energy Systems Group, plans to apply to fellowships and graduate programs in EECS, applied math, and operations research.

Based on her analysis, Liu says that the market could effectively determine the price and availability of charging stations. Offering incentives for EV owners to charge during the day instead of at night when demand is high could help avoid grid overload and prevent extra costs to operators. “People would still retain the ability to go to a different charging station if they chose to,” she says. “I’m arguing that this works.”

How Much Is a New Car Battery?

Ever found yourself stuck on the side of the road, cursing under your breath as your car refuses to start? Maybe you’ve been there, stranded with a dead battery, wondering, “How much is this going to set me back?” Don’t worry—you’re not alone! Replacing a car battery is something most drivers face at some point, and the cost can vary quite a bit. On average, a new car battery will run you between $50 and $200, but the final price depends on a handful of factors we’re about to unpack. Stick with me, and by the end of this, you’ll know exactly what drives those costs, the best places to buy a battery, and even what installation might add to your bill. Ready to dive in?

Factors Affecting Car Battery Prices So, why does one battery cost $50 while another hits $200? It’s not just random pricing magic—it’s about understanding a few key variables. Knowing these can help you budget smarter and pick the perfect battery for your ride. After all, nobody wants to overspend on fancy features they don’t need or get stuck with a battery that can’t handle their car’s demands. Let’s break it down.

Type of Battery Ever wondered why some batteries seem way pricier than others? It often boils down to the type. Here’s the scoop:

Standard Lead-Acid: This is the trusty old workhorse of car batteries. Affordable and reliable, it’s perfect for older vehicles without a lot of tech. Think of it as the classic flip phone of batteries—it gets the job done! AGM (Absorbent Glass Mat): These are a step up, built for modern cars with start-stop systems or extra gadgets. They cost more, but they’re worth it if your car needs that extra oomph. Comparing AGM vs lead-acid batteries? AGM wins for high-demand vehicles. EFB (Enhanced Flooded Battery): A solid middle-ground option. It’s tougher than standard lead-acid but won’t break the bank like AGM. Great for durability on a budget. Lithium-Ion: The premium choice for hybrids or electric vehicles. They’re pricey—sometimes over $200—but they’re lightweight and powerful, like the sports car of batteries. Fun fact: According to Consumer Reports, AGM batteries are becoming more popular as cars get techier, with sales jumping 15% in the last five years.

Brand When it comes to brands, you often get what you pay for. Heard of Optima or DieHard? These big names are like the Apple or Samsung of car batteries—reliable, high-performing, and, yes, a bit more expensive. You might shell out $150 or more, but they’re trusted for a reason. On the flip side, generic brands can save you cash upfront—sometimes as low as $50—but they might not last as long. It’s like choosing between a quality pair of boots or a cheap knockoff. Personally, I’d lean toward a trusted brand to dodge the headache of a dead battery too soon, but if money’s tight, generics can work—just don’t expect miracles!

Size and Capacity Size and capacity matter more than you might think. Here’s how it works:

Group Size: This is about the battery’s physical fit—like buying the right shoe size. Common sizes like Group 24 or 35 vary by vehicle, and bigger ones cost more. Check your owner’s manual to avoid a mismatch! Cold Cranking Amps (CCA): Ever tried starting your car on a freezing morning? CCA measures how well reiterate power a battery pumps out in the cold. Higher CCA means a higher price, but it’s a lifesaver in chilly climates. Ampere-Hours (Ah): This is the battery’s “fuel tank”—how long it can power stuff. Bigger vehicles or ones with lots of electronics need more Ah, which bumps up the cost. A quick tip: AAA says batteries with higher CCA can reduce winter breakdowns by up to 25%—worth it if you’re in a frosty spot!

Technology Modern cars come with cool tricks like start-stop systems, where the engine shuts off at stoplights to save gas. But these need batteries—like AGM or EFB—that can handle constant recharging. It’s like needing a fast-charging phone battery—you pay extra for the tech. These advanced features can add $20-$50 to the price, but they’re a must for newer models.

Where to Buy a Car Battery Okay, you’ve got the lowdown on what affects the price—now, where should you snag your battery? Your choice impacts not just cost but convenience and extras like installation. Do you care more about price, speed, or someone else doing the dirty work? Let’s explore the options.

Dealerships Buying from a dealership gets you an OEM (Original Equipment Manufacturer) battery—the exact kind your car rolled out with. Plus, they’ll usually install it for you. It’s like getting a tailor-made suit—perfect fit, no fuss. But here’s the catch: prices often range from $150 to $250. If you value peace of mind and don’t mind the splurge, this might be your pick.

Auto Parts Stores (e.g., AutoZone, Advance Auto Parts) These spots are gold for variety and value. You’ll find batteries from $80 to $200, and the staff can often point you to the right one. Bonus: Some, like AutoZone, offer free testing and installation. Not every store does, though, so call ahead. It’s a solid middle ground for DIY fans or anyone hunting for the best place to buy a car battery.

Online Retailers (e.g., Amazon, BatteryMart) Love shopping in your pajamas? Online retailers offer batteries from $50 to $150, delivered right to your door. Sounds sweet, right? But watch out—shipping can tack on $10-$20, and you might wait a few days. Plus, you’re on your own for installation. Great for deal-hunters who don’t mind a little elbow grease.

Big-Box Stores (e.g., Walmart, Costco) For budget shoppers, big-box stores are a win. Batteries here run $50 to $120, and returns are a breeze if something goes wrong. Selection’s slimmer, though, and installation? Rare. If you’re comfy swapping it yourself, this could save you some serious cash.

Oh, and here’s a stat: A AAA survey found 30% of roadside calls are battery-related, so wherever you buy, don’t skimp on quality!

Installation Costs So, you’re getting a new car battery—awesome! But have you thought about how it’s actually going to get into your car? Installation isn’t just a tiny detail; it can totally change how much you end up spending. Whether you roll up your sleeves or hand it off to a pro, here’s the lowdown on your options.

DIY Installation Cost: Free (as long as you’ve got a wrench, some gloves, and maybe a YouTube video handy). What’s the Deal?: If you’re the “I can fix anything” type, doing it yourself might sound like a win. You save some cash—score! But hold up: it’s not like swapping out a dead AA battery in your remote. You’ve got to connect everything just right, or your car might not start. Worse, you could fry something important (yep, that’s a real risk). Ever tried fixing something and ended up with extra screws? Imagine that, but with your car. I’d say give it a shot if you’re confident, but don’t wing it—check a guide first! Cool Stat: A AAA survey found that 20% of drivers have tackled DIY car fixes, but almost half messed up somewhere along the way. So, you’re not alone if it’s trickier than it looks! Cost: $0 (if you own tools) Risks:

20% of DIYers damage their vehicle’s electrical system during installation (AAA Survey) 47% of jump-start failures trace to improper battery connections (Car Care Council) Tool Requirements:

Basic wrench set (15−15−50) Anti-corrosion spray ($5) Voltage tester ($20) (Recommended by Popular Mechanics)

Pro Tip: Watch our step-by-step installation guide to avoid the 32% error rate first-timers face.

Professional Installation Cost: Usually $20-$50, though places like AutoZone might hook you up for free if you buy from them. What’s the Deal?: Not feeling the DIY vibes? No biggie! Paying a pro to install your battery is like having someone else cook dinner—sure, you could do it, but why stress? These folks know their stuff, so your battery’s set up safely and won’t leave you stranded. Plus, free installation deals are out there, which is basically a high-five from the universe. Honestly, I’d pick this every time—less headache, more “done right” vibes. Quick Tip: Call ahead or check online—some shops sneak in fees, while others surprise you with a free install. Who doesn’t love a bonus? Cost Range:

Free at AutoZone/O’Reilly’s with battery purchase (Retailer Policy) 20−20−50 at independent shops (RepairPal) $75+ at dealerships (Consumer Reports) Benefits:

100% warranty compliance (vs. 68% for DIY) (Battery Council International) Free diagnostics (checks alternator/charging system) Hazard prevention – 9V batteries can spark explosions if mishandled (OSHA Safety Alert) Money-Saver: Chains like Walmart offer free installation on 90% of batteries sold (Retail Dive). Want to know more, visit our website…

Warranties Okay, picture this: you buy something pricey, and a week later, it breaks. Total bummer, right? That’s where warranties come in clutch with car batteries. They’re like a promise that your battery won’t leave you hanging—or at least, not without some backup. A good warranty can make spending a bit more upfront feel like a no-brainer. Here’s what you need to know.

Typical Warranty Periods Standard Batteries: 1-3 years. Premium Batteries: Up to 4-5 years. It’s like picking between a cheap umbrella and a sturdy one—the better one lasts longer. Premium batteries (think AGM or high-end brands) often come with longer warranties because they’re built tougher. Makes sense, right?
