A meddling high king

Elrond x Male!Elf!Reader

Summary:High King Gil-Galad conspires to bring his herald closer to one of his guards

Just a short one while I figure stuff out for By Moonlight! I might want to do some rings of power requests soon, I have a few smutty ideas ( •̀ .̫ •́ )✧

Heavy is the head that wears the crown and Gil-Galad's head certainly felt like lead these days. With Galadriel's concerns and pointless meetings with ambitious courtiers he felt he was well justified in making a little bit of fun.

His newest project had been born of an old bit of entertainment grown stale. Despite his heralds silver tongue he had yet to woo the object of his affection. In fact as of late Gil-Galad had become convinced Elrond may not even realise his own feelings. How he could remain so oblivious was beyond him however. As every eloquent word seemed to leave Elrond in the presence of one of Lindon's guards.

Gil-Galad was fond of this guard himself, though it was an entirely platonic appreciation. He was just a very calming presence. No fawning or awkwardness under the scrutiny of his High King, just a dutiful quiet man. Though Gil-Galad was far too observant not to notice his albeit subtle reactions to Elrond's presence.

Just last week he'd watched as Elrond took notes in a meeting with a rather dull member of the court. Y/n had stood against the wall, ready for his call but Gil-Galad noted his eyes shifting back to his herald as the hours dragged on.

Then Elrond had paused in his note taking. His curls had fallen into his face, haven grown long as of late. He swept them back, his fingers splaying and running through the waves and just for a moment Gil-Galad watched his guard stiffen.

Then not two days prior Gil-Galad had spied Elrond's attempts at conversation with the man. The ellon who wrote his speeches, who prided himself on his recall of poetry and prose, now fumbled over simple small talk.

Gil-Galad believed he'd meant to make some comment on the unseasonable chill but had somehow so expertly fumbled his words as to imply his guard was standoffish and cold. Then in a spectacular display of stuttered half sentences manged to call him foolish and then trip over the low wall of the garden.

Any man would've been right to let him land face first in the shrubbery but not Y/n. He'd instead caught the buffoon and pulled him swiftly to his feet and right into his arms. Then as if he couldn't have made Elrond blush deeper he'd laughed heartily. Such a sudden and melodic sound that Gil-Galad himself was surprised it came from his quiet guard. Then to seal the deal had told the quickly reddening ellon that any day would be warmed by his company.

Yet, Gil-Galad noted, neither had made any move to begin a courtship. He supposed his guard may feel it inappropriate to engage in such behaviour with another in service to himself. Though perhaps not, as Gil-Galad had approved of many such unions in his presence. So it may be something a lot simpler though uncharacteristic of a man he'd seen leap into ravenous warg's path without a second thought.

He was scared.

Thus, as all things, it seemed to fall into Gil-Galad's hands to rectify the situation. So when opportunity struck he sent his favoured guard along side Elrond and Celebrimbor. Gil-Galad smiled into his goblet at the thought of the journey. Of Elrond and Y/n spending hours trekking together. Growing comfortable in each others presence.

He could just imagine Elrond's flushed expression when they'd arrive at Eregion. Where a Lord's duties would pull Celebrimbor from the group and leave them alone at last. Would they stroll together in the cities gardens? Take a trip past the bridge to lunch at the river banks? Could Elrond steady his heart long enough to recite a few verses?Would he come to see Y/n's admiration? Whatever they did he did not suppose it mattered, after all they'd be in each others company and that'd be enough.

Closing in on superconducting semiconductors

New Post has been published on https://sunalei.org/news/closing-in-on-superconducting-semiconductors/

Closing in on superconducting semiconductors

In 2023, about 4.4 percent (176 terawatt-hours) of total energy consumption in the United States was by data centers that are essential for processing large quantities of information. Of that 176 TWh, approximately 100 TWh (57 percent) was used by CPU and GPU equipment. Energy requirements have escalated substantially in the past decade and will only continue to grow, making the development of energy-efficient computing crucial. 

Superconducting electronics have arisen as a promising alternative for classical and quantum computing, although their full exploitation for high-end computing requires a dramatic reduction in the amount of wiring linking ambient temperature electronics and low-temperature superconducting circuits. To make systems that are both larger and more streamlined, replacing commonplace components such as semiconductors with superconducting versions could be of immense value. It’s a challenge that has captivated MIT Plasma Science and Fusion Center senior research scientist Jagadeesh Moodera and his colleagues, who described a significant breakthrough in a recent Nature Electronics paper, “Efficient superconducting diodes and rectifiers for quantum circuitry.”

Moodera was working on a stubborn problem. One of the critical long-standing requirements is the need for the efficient conversion of AC currents into DC currents on a chip while operating at the extremely cold cryogenic temperatures required for superconductors to work efficiently. For example, in superconducting “energy-efficient rapid single flux quantum” (ERSFQ) circuits, the AC-to-DC issue is limiting ERSFQ scalability and preventing their use in larger circuits with higher complexities. To respond to this need, Moodera and his team created superconducting diode (SD)-based superconducting rectifiers — devices that can convert AC to DC on the same chip. These rectifiers would allow for the efficient delivery of the DC current necessary to operate superconducting classical and quantum processors.

Quantum computer circuits can only operate at temperatures close to 0 kelvins (absolute zero), and the way power is supplied must be carefully controlled to limit the effects of interference introduced by too much heat or electromagnetic noise. Most unwanted noise and heat come from the wires connecting cold quantum chips to room-temperature electronics. Instead, using superconducting rectifiers to convert AC currents into DC within a cryogenic environment reduces the number of wires, cutting down on heat and noise and enabling larger, more stable quantum systems.

In a 2023 experiment, Moodera and his co-authors developed SDs that are made of very thin layers of superconducting material that display nonreciprocal (or unidirectional) flow of current and could be the superconducting counterpart to standard semiconductors. Even though SDs have garnered significant attention, especially since 2020, up until this point the research has focused only on individual SDs for proof of concept. The group’s 2023 paper outlined how they created and refined a method by which SDs could be scaled for broader application. 

Now, by building a diode bridge circuit, they demonstrated the successful integration of four SDs and realized AC-to-DC rectification at cryogenic temperatures. 

The new approach described in their recent Nature Electronics paper will significantly cut down on the thermal and electromagnetic noise traveling from ambient into cryogenic circuitry, enabling cleaner operation. The SDs could also potentially serve as isolators/circulators, assisting in insulating qubit signals from external influence. The successful assimilation of multiple SDs into the first integrated SD circuit represents a key step toward making superconducting computing a commercial reality. 

“Our work opens the door to the arrival of highly energy-efficient, practical superconductivity-based supercomputers in the next few years,” says Moodera. “Moreover, we expect our research to enhance the qubit stability while boosting the quantum computing program, bringing its realization closer.” Given the multiple beneficial roles these components could play, Moodera and his team are already working toward the integration of such devices into actual superconducting logic circuits, including in dark matter detection circuits that are essential to the operation of experiments at CERN and LUX-ZEPLIN in at the Berkeley National Lab.

This work was partially funded by MIT Lincoln Laboratory’s Advanced Concepts Committee, the U.S. National Science Foundation, U.S. Army Research Office, and U.S. Air Force Office of Scientific Research.

AC-DC Rectifier: Bridging Two Worlds of Power

Imagine a world without electricity conversions — where your laptop won’t charge, your phone stays dead, and industrial motors fail to operate. Unthinkable, right? What stands between AC power from the grid and your DC-powered electronics is an essential, often invisible device: the AC-DC Rectifier.

Despite being critical to everything from daily gadgets to complex aerospace systems, the rectifier rarely gets credit for the massive transformation it enables. Let’s change that.

From Alternating to Direct – Why It Matters

Alternating Current (AC) is how electricity travels through our power grids. It’s efficient for long-distance transmission, easy to step up or down in voltage, and suitable for large-scale energy distribution. However, most electronics — your smartphone, LED lights, electric vehicles, and even high-end servers — run on Direct Current (DC).

So how do we bridge this gap?

Enter the AC-DC Rectifier, the vital converter that transforms grid-fed AC into usable DC. It’s not just about electricity; it’s about adaptation — evolving the flow of energy to meet the needs of technology. And in that transformation lies an intricate blend of science, design, and application.

A Story You Can Relate To

Meet Priya, an electrical engineer at a solar microgrid company in Rajasthan. Her challenge wasn’t lack of solar energy; it was inconsistent performance from stored power. The culprit? Cheap, inefficient rectifiers that distorted the signal and degraded batteries.

When Priya introduced industrial-grade AC-DC Rectifier modules with controlled ripple and thermal protection, battery life improved by 30%, and the system uptime went up dramatically. What seemed like a simple switch turned out to be a major performance boost — something her team hadn't fully anticipated until they saw it in action.

The rectifier wasn’t just a component anymore — it was an enabler.

The Tech Under the Hood

So how exactly does an AC-DC Rectifier work?

At its core, rectification involves converting a sinusoidal AC wave into a linear DC line. This is achieved through the use of diodes, thyristors, or MOSFETs, depending on complexity and application.

1. Half-Wave Rectification

Only the positive half of the AC signal is allowed to pass through. It’s simple, but inefficient and used only in low-demand circuits.

2. Full-Wave Rectification

Both halves of the AC waveform are utilized. With the help of bridge rectifiers, the output is more consistent, ideal for higher-power applications.

3. Controlled Rectifiers

These use semiconductor devices like SCRs or IGBTs, allowing engineers to control output voltage levels — essential for motor speed controllers and battery chargers.

4. Filtered Rectifiers

To reduce “ripple” — the leftover wave-like behavior in DC — capacitors and inductors are added to smooth out the flow.

Each rectifier type serves different needs, from tiny phone chargers to complex power supplies in industrial automation.

Why It Matters More Than Ever

The rise of DC-based technologies makes AC-DC Rectifier systems even more critical today than they were a decade ago.

1. Electric Vehicles (EVs)

Charging stations rely heavily on rectifiers to ensure batteries receive pure, stable DC. A poor rectifier can shorten battery life and reduce driving range.

2. Renewable Energy

Solar panels generate DC, but many systems need AC to interface with the grid — and vice versa. Modern energy systems use rectifiers to maintain voltage stability.

3. Data Centers

Servers operate on DC. Rectifiers convert incoming AC to keep massive infrastructure running smoothly — a split-second glitch can cause thousands in downtime.

4. Medical Devices

Precision instruments like MRI machines or ventilators require pure, distortion-free DC. This level of quality is only possible through specialized rectifiers.

Humanizing the Current

Let’s not reduce this technology to circuits and silicon. The AC-DC Rectifier is a guardian of stability. When you’re working late on a presentation, your laptop humming reliably — thank the rectifier. When hospitals maintain life-support systems during a blackout with the help of inverters and UPS systems — thank the rectifier. When satellites silently collect data while orbiting Earth — again, thank the rectifier.

It doesn’t just convert voltage; it converts possibilities into realities.

The New Era of Smart Rectifiers

Thanks to advancements in power electronics, today’s rectifiers are smarter, more efficient, and application-specific.

Wide Bandgap Semiconductors (SiC, GaN): They allow for faster switching, higher temperatures, and smaller components. Great for high-frequency and aerospace applications.

Digital Control Systems: Feedback-based systems help monitor current, correct fluctuations, and adjust to real-time demand.

Energy Recovery: Some modern rectifiers are designed to push unused energy back into the grid or battery systems.

Modular Rectifier Systems: Ideal for scaling power supplies. Need more output? Just plug in another rectifier module.

Tips When Choosing an AC-DC Rectifier

Whether you're an engineer, project manager, or someone setting up a high-powered system, here’s what to consider:

Power Rating: Match it to your load requirements.

Input Voltage Range: Ensure flexibility for different global standards.

Efficiency (>90%): Better efficiency means less heat and lower power bills.

Thermal Management: Good rectifiers come with built-in cooling or heat sink options.

Certifications: UL, CE, or ISO depending on the region and industry.

EMI Filtering: Reduces interference in sensitive systems.

Redundancy Features: In mission-critical applications like healthcare or aviation, dual rectifiers with automatic failover are a must.

Final Thoughts: More Than a Converter

The next time you plug in a charger, boot up a server, or admire an EV silently gliding past, remember — an AC-DC Rectifier is working behind the scenes. It's the bridge between chaotic currents and calm, directed energy. It's not just about volts and amps; it's about reliability, precision, and trust.

If you're building or maintaining systems where power matters — give the rectifier its due importance. Because in a world that runs on conversions, AC-DC Rectifier technology is the unsung foundation of modern energy infrastructure.

What Does a Rectifier Do? 

Introduction to Rectifiers  

A rectifier is an essential electrical device that converts alternating current (AC) to direct current (DC). AC power fluctuates in polarity, making it unsuitable for devices requiring a steady voltage. Rectifiers ensure a one-directional flow of current by blocking the negative half of the AC cycle or converting it entirely. They are widely used in power supplies, electronic circuits, and battery charging applications. Depending on the configuration, rectifiers can improve efficiency, reduce power losses, and provide stable DC output essential for various electronic and industrial applications.  

Types of Rectifiers  

Rectifiers come in different types based on their design and operation. The most common are half-wave, full-wave, and bridge rectifiers. A half-wave rectifier allows only one half of the AC cycle to pass, while a full-wave rectifier utilizes both halves, providing better efficiency. Bridge rectifiers, a type of full-wave rectifier, use four diodes to maximize current conversion with minimal power loss. The choice of rectifier depends on application requirements such as voltage stability, efficiency, and ripple factor.  

Working Principle of a Rectifier  

Rectifiers function using diodes, which allow current to flow in only one direction. In a half-wave rectifier, a single diode blocks one-half of the AC cycle, producing a pulsating DC output. Full-wave rectifiers, whether center-tap or bridge type, use multiple diodes to rectify both halves of the AC waveform, resulting in smoother DC output. The rectified signal often requires filtering through capacitors or inductors to reduce voltage fluctuations and improve performance in sensitive electronic circuits.  

Applications of Rectifiers  

Rectifiers are integral to many electrical and electronic systems. They are used in power supplies for household appliances, industrial machinery, and communication systems. Battery chargers employ rectifiers to convert AC power into DC for recharging. In automotive applications, rectifiers regulate voltage in alternators to provide stable power to vehicle electronics. Additionally, they play a crucial role in renewable energy systems, converting AC generated by wind turbines and solar inverters into usable DC power.  

Advantages and Limitations  

Rectifiers offer numerous advantages, including efficient AC-to-DC conversion, low power losses, and reliable performance in various applications. Bridge rectifiers, in particular, provide higher efficiency by utilizing both halves of the AC cycle. However, rectifiers also have limitations, such as voltage ripple, which requires additional filtering components for smooth DC output. Power dissipation in diodes can lead to heat generation, necessitating heat sinks in high-power applications. Despite these challenges, rectifiers remain indispensable in modern electrical and electronic systems.

Review, teardown, and testing of ERPF-400-24 Mean Well power supply

General Description

Brief Specification: ERPF-400-24 is a power supply unit with a 24-volt DC output and a rated current of up to 16.7 amps. According to the specification, the unit has an extended operating range for AC input voltage from 90 to 264 V. However, with an input voltage between 90 and 200 V, the unit can only deliver 50% of its rated power.  It can also operate from a DC input within the range of 127 to 370 V.

The unit has dimensions of around 9x5x2 inches (220x130x48 mm exactly), is built on a printed circuit board housed in a stamped metal case, and is designed to operate with no forced cooling. The board is installed into the case, like in a tray, and is covered with a compound (most likely thermally conductive), making it non-removable for repair. The unit is covered with a perforated lid on top.

It features an LED indicator for output voltage and allows adjustment of the output voltage within a range of -5% to +10%. The unit includes an active PFC (Power Factor Correction) circuit and has a high power factor of up to 0.98 at 115 VAC. It also has thermal protection, with temperature monitoring performed using a thermistor placed on the output rectifier diodes. Traditional safe measures, such as overload and overvoltage protection, are also provided.

Circuit and construction description: Unfortunately, the compound filling makes detailed examination of the circuit difficult, so there is a high probability of interpretation errors. However, it appears that the design shares many similarities with the RSP-320-24 (https://teardownit.com/posts/review-teardown-and-testing-of-rsp-320-24-mean-well-power-supply) power supply unit, in both circuit and layout. This suggests that the ERPF-400 may be controlled by the FAN4800 controller, just like the RSP-320.

The input and output terminals are mounted on a common screw terminal block (1). The terminal block's connections from top to bottom are as follows: three terminals for phase, neutral, and ground (input), and three parallel terminals for the output, ground, and +24V. The input voltage from the terminal block (1) passes through an EMI filter (3) and then to the diode bridge (5). A varistor (2) is installed at the filter's input to suppress dangerous voltage spikes. The rectified voltage from the bridge (5) is then routed through an NTC inrush current limiter (4) to the active PFC circuit. The PFC's power stage consists of a transistor (6), inductor (11), diode (7), and output capacitor (8). The rectified and filtered voltage from capacitor (8) is fed into a forward converter, which comprises transistors (9) and transformer (10). The voltage from the transformer's output winding (10) is rectified by diodes (12) and filtered by an output LC filter (13) (14).

The filter’s output capacitance is provided by four 560µF, 35V capacitors rated for operation at up to 220°F or 105°C (13).

The transformer's core (10) is tied in a metal clamp, which is bolted to the case. This design likely serves to dissipate heat from the transformer.

Due to the presence of the compound, it is difficult to assess the overall build quality. The compound itself has been applied somewhat carelessly, with visible splatters and drips. Furthermore, there are gaps in the compound application, significantly reducing its protective effectiveness.

The LED output voltage indicator and output voltage adjustment resistor (16) are located near the terminal block, allowing access without removing the top cover.

Test Conditions

Most tests were conducted using Test Circuit 1 (see appendix) at 80°F (27°C), 70% humidity, and 29.8 inHg pressure. Unless otherwise specified, measurements were taken without pre-warming the power supply, and the operating mode was momentary load. Input voltage was set to 115V AC, and the current of 8.4 A was considered 100%. The following values were used to determine load levels:

Output voltage with static load

The unit demonstrates excellent output voltage stability.

Startup Characteristics

Startup at 100% load

Before the test, the power supply was turned off for at least 5 minutes with the load connected at 100%. The startup waveform at 100% load is shown below (Channel 1: output voltage, Channel 2: input current):

The startup process can be divided into three phases: 1. Input current pulses charging the input capacitors upon connection to the grid, with a peak amplitude of about 3 A, consisting of two portions of one period each. 2. Waiting for the control circuit to start, about 231 ms. 3. (Output Voltage Rise Time) Output voltage rise, 57 ms. 4. (Turn On Delay Time) The total time to reach operational mode from power-on is 288 ms.

(Output Voltage Overshoot) The startup process is aperiodic with no overshoot.

Startup at 0% load

Before the test, the power supply was turned off for at least 5 minutes with the load connected at 100%, then the load was disconnected, and the unit was turned on. The startup waveform at 0% load is shown below:

The startup process consists of three phases: 1. Input capacitors charging upon connection to the grid, with a peak amplitude of about 2.6 A, consisting of two portions of one period each. 2. Waiting for the control circuit to start, about 241 ms. 3. (Output Voltage Rise Time) Converter startup, output voltage rise, and transition to operational mode, 56 ms. (Turn On Delay Time) The total time to reach operational mode from power-on is 297 ms.

(Output Voltage Overshoot) The startup process is aperiodic with no overshoot.

Shutdown Characteristics

The shutdown process was tested at 100% load with nominal input voltage at the moment of shutdown. The shutdown waveform is shown below:

The shutdown process can be divided into two phases: 1. (Shut Down Hold Up Time) The unit continues operating, powered by the charge stored in the input capacitors, until their voltage drops to a critical level at which maintaining the output voltage is no longer possible. This phase lasts for 26 ms. 2. (Output Voltage Fall Time) Output voltage decline, converter stop, and acceleration of the voltage drop. This phase lasts for 25 ms.

(Output Voltage Undershoot) The shutdown process is aperiodic, with no undershoot.

Current amplitude at 100% load prior to shutdown was 2.8 A.

Output voltage ripple

At 100% load:

low-frequency ripple of about 10-12 mVp-p at twice the grid frequency, and around 4 kHz with a ripple of 13-15 mVp-p.

At the converter frequency, ripple is approximately 25 mVp-p, with noise at 120 mVp-p.

At 75% load:

low-frequency ripple of about 10 mVp-p at twice the grid frequency and around 12 mVp-p at approximately 4 kHz.

Converter frequency ripple is about 20 mVp-p, with noise at 100 mVp-p.

At 50% load:

low-frequency ripple of about 10 mVp-p at twice the grid frequency and around 15 mVp-p at approximately 4 kHz.

Converter frequency ripple is about 20 mVp-p, with noise at 100 mVp-p.

At 10% load:

low-frequency ripple of about 3-5 mVp-p.

Converter frequency ripple is about 20 mVp-p, with noise at 100 mVp-p.

At 0% load:

The input current was measured with a multimeter at 60 mA. (Power Consumption) Input current in this mode is primarily reactive in nature; thus, the power consumption value measured with handy instruments can't be correct. The input filter has two capacitors, according to the diagram.

At 0% load, low-frequency ripple is hardly distinguishable from the noise, about 3 mVp-p.

Converter frequency ripple is masked by noise around 100 mVp-p.

Dynamic characteristics

Dynamic characteristics were assessed in a mode that switches between 50% and 100% load. The oscillogram below illustrates the process:

It is evident that the unit's response to step-load changes is aperiodic, with the magnitude of the response to load changes being approximately 100 mV p-p.

Overload protection

The manufacturer specifies overload protection with a constant current limiting type, which was confirmed during testing. When overloaded or the output terminals are shorted, the unit enters current limiting mode and automatically recovers after the fault is removed.

The output current at which the limit is triggered is 22 A.

Input safety assessment

(Input Discharge) The input circuit discharge time constant was measured upon disconnection from the grid, with a value of 0.245 s. This means that when operating on a 120V grid, the time required for the input circuits to discharge to safe levels (<42 V) is 0.39 s:

Important: This result applies only to the tested unit and was obtained exclusively for research purposes. It cannot, under any circumstances, be considered a guarantee of safety.

The ground leakage current was measured at 73µA.

Thermal behavior

No significant heating of components was observed during no-load operation. Thermograms were taken at three power levels—80%, 90%, and 100%—with and without the top cover. The thermograms show that the most thermally loaded components of the unit are the NTC inrush current limiters (4), which stand out from the other components. At 80% load, the NTC temperature is 175.6°F (80°C, with a 53°C rise above ambient temperature); at 90% load, it reaches 192.1°F (89°C, with a 62°C rise); and at 100% load, it reaches 203.9°F (95.5°C, with a 68.5°C rise).

The second hottest component, after the NTC, is a resistor, 25 degrees cooler.

Conclusions

The ERPF-400-24 generally exhibits low noise and ripple, and it maintains good accuracy in sustaining the output voltage. The unit has decent dynamic characteristics, responding to pulsating loads without overshoot.

On the startup waveform (see oscillograms), there is an N-shaped section where, after the initial rise in output voltage, a partial drop occurs, followed by another rise and stabilization at the nominal level. This behavior could potentially cause issues when powering up digital devices that require initialization.

The build quality is good. However, the compound is applied somewhat poorly, with notable imperfections and several gaps. Unfortunately, these gaps affect components with increased hygroscopicity, particularly the wire-wound inductances of the output and input noise filters. Despite the manufacturer's claim of “protecting the internal electronic components from rain splash and dust,” this unit should not be used without additional water ingress protection.

According to the specifications, the unit is designed for operation under conditions of "Cooling by free air convection" and "-22F ~ +140°C (Refer to output load derating curve)." The tested unit indeed remains safe up to 100% load during continuous operation. The presence of a temperature sensor on the rectifier diodes adds extra assurance of safety.

Important: The results and conclusions presented apply only to the tested unit and were obtained solely for research purposes. Under no circumstances should they be used to assess all devices of this type.
