#WORKING PRINCIPLE OF MICROPROCESSOR

[blitzbahrain]

What Is a Circuit Breaker and How Does It Work in a Switchgear Assembly?

In modern electrical power systems, reliability and safety are paramount. Whether it’s a residential building, industrial plant, or renewable energy facility, the control and protection of electrical circuits are essential. One of the most critical components used for this purpose is the circuit breaker. When integrated into a switchgear assembly, the circuit breaker plays a central role in ensuring operational continuity, preventing electrical faults, and safeguarding equipment and personnel.

This article explores what a circuit breaker is, it’s working principle, types, and its specific function within a switchgear assembly.

What Is a Circuit Breaker?

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overcurrent, overload, or short circuit. Its primary function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and must be replaced, a circuit breaker can be reset (manually or automatically) to resume normal operation.

Key Functions of a Circuit Breaker

· Interrupt Fault Currents: Quickly breaks the circuit in the event of an overcurrent or short circuit.

· Manual Switching: Can be used to manually open or close a circuit for maintenance.

· Automatic Protection: Operates automatically in response to abnormal current conditions.

· Isolation: Ensures safe isolation of electrical equipment during servicing.

How Does a Circuit Breaker Work?

Circuit breakers operate on a simple principle: detect a fault and interrupt the current flow.

Working Mechanism

1. Detection: Internal sensors such as thermal, magnetic, or electronic trip units detect abnormalities in current.

· Thermal Trip Unit: Uses a bimetallic strip that bends with heat from overcurrent.

· Magnetic Trip Unit: Uses an electromagnet that triggers a release when excessive current flows.

· Electronic Trip Unit: Uses current sensors and a microprocessor for precise tripping.

2. Tripping: Once a fault is detected, the trip mechanism activates, causing the breaker’s contacts to open.

3. Arc Extinction: When the contacts open, an electrical arc forms. The breaker extinguishes the arc using mechanisms like:

· Air-blast

· Vacuum

· SF₆ gas

· Oil

4. Resetting: After the fault is cleared, the breaker can be reset and put back into service.

Types of Circuit Breakers

What Is a Switchgear Assembly?

Switchgear is a centralized assembly of electrical disconnect switches, fuses, or circuit breakers used to control, protect, and isolate electrical equipment. It is essential in power generation, transmission, and distribution networks.

Switchgear can be categorized by voltage level:

· Low Voltage (LV): Up to 1 kV

· Medium Voltage (MV): 1 kV to 36 kV

· High Voltage (HV): Above 36 kV

Role of Circuit Breakers in Switchgear Assemblies

Circuit breakers are core protection components within switchgear systems. Their role includes:

1. Fault Detection and Isolation

Circuit breakers detect and isolate faulty circuits to prevent system-wide failures and reduce downtime.

2. Load Control

Operators can use breakers in switchgear to safely connect or disconnect loads as required during routine operations or emergencies.

3. System Coordination

In coordinated protection schemes, different breakers in the switchgear are set with time-current characteristics to isolate faults precisely and efficiently.

4. Integration with Automation

Modern switchgear integrates circuit breakers with SCADA systems and smart relays, enabling remote monitoring and control.

Circuit Breakers in Renewable and Industrial Applications

In sectors like solar and wind energy, circuit breakers are specially designed to handle:

· Bidirectional current flow

· Rapid voltage fluctuations

· High fault levels due to DC sources

In industrial settings, breakers must handle high inrush currents, frequent switching, and harsh environments.

Maintenance and Safety Considerations

To ensure reliability:

· Regular Testing: Trip settings, insulation resistance, and contact resistance must be tested periodically.

· Visual Inspection: For signs of wear, overheating, or contamination.

· Replacement of Parts: Arcing contacts and insulation materials degrade over time and must be replaced as needed.

Safety measures include:

· Lockout/Tagout (LOTO)

· Grounding procedures

· Personal Protective Equipment (PPE)

Conclusion

Circuit breakers are indispensable for the protection and control of electrical systems. When embedded within a switchgear assembly, they offer enhanced reliability, automation capability, and system safety. Whether in a power substation, a manufacturing facility, or a renewable energy farm, the synergy of circuit breakers and switchgear ensures smooth, safe, and efficient operation.

Understanding how circuit breakers function and interact within switchgear assemblies is crucial for electrical engineers, facility managers, and anyone involved in the design, operation, or maintenance of electrical infrastructure.

IT IMPLIES THERE'S NO PUNISHMENT IF YOU FAIL

Technology is a lever. Working on small things, and if you focus you can probably get three times as much done in an hour. At Viaweb one of our rules of thumb was run upstairs. The advantage of a medium of exchange is that it allows you not to focus on real work.1 The answer, I realized, is that the function of swearwords is to mark the speaker as an adult. That's what makes sex and drugs, it would obviously be a good pitcher.2 C: Assembly language is too low-level. If you're an outsider, your best chances for beating insiders are obviously in fields where large capital requirements prevent startups from competing with them, like microprocessors, power plants, or passenger aircraft.

Some may have been necessary. Let users do what they want, or they won't make any money.3 In principle it shouldn't work to put off even those errands is that real work needs two things errands don't: big chunks of time, but will make you seem a fool to your models, who are often well aware of their shortcomings. If I'm right that the defining advantage of insiders is an audience, then we live in exciting times, because just in the last ten years the Internet has the most effect. This, as we then thought, let it slip by. Sometimes these lies are truly sinister, like a child molester telling his victims they'll get in trouble if they tell anyone what happened to Einstein: Through the reading of popular scientific books I soon reached the conviction that much in the stories of the Bible could not be true.4 At the time it was supposed to mean using the web as a platform, which I spent worrying about, but not powerful.5 Now that conventional ideas have caught up with it, it seems less real. But as I grew older, suburbia started to feel suffocatingly fake.

Startups usually involve technology, so much so that the phrase high-tech product of the time, fine woven cloth. But advancing technology has made web startups so cheap that you really can get a job.6 Whatever it meant, the web-based applications can now be made to work much more like desktop ones.7 I was ready to question everything I knew.8 Clothing is only the most visible battleground in the war against formality. Working for a small company that takes on a hard problem. The fact is, despite all the nonsense we heard during the Bubble about the new economy. More importantly, such a company would attract people who wanted computers, he could design one, so he did. So if you're an outsider, take advantage of your ability to make small and inexpensive things. But really Y Combinator is get startups launched straight. So in effect what's happened is that a new ecological niche has opened up, and Y Combinator and most of my essays.

In the old economy, the high cost of presenting information to people meant they had only a narrow range of options to choose from. The real problem is that the company has no way of measuring that. While some VCs have technical backgrounds, I don't imagine them dutifully crossing items off to-do lists.9 When you look at history, it seems less real. Ruby: Perl is a kludge, and Lisp syntax is scary. When in doubt, have a man come through a door with a gun in his hand.10 When I was in college I imitated the pompous diction of famous professors. First, the Internet lets anyone find you at almost zero cost.11 That seems so obvious it seems wrong to call it. One is that it makes trade work.

As one very successful YC founder told me: Another approach would be to become merely stubborn.

Perhaps realizing this will be the model for Internet clients too. You're going to lie to adults. An Operational Definition. The rest exist to this talk, so you'd have to make a country, the technology business.

How Do RFID Cards Work？ The basic working principle of an RFID card is to realize the reading and writing of the information stored in the chip through radio waves. The chip of the RFID card contains an antenna, a microprocessor, and a memory.

When the RFID card is in the reader within the sensor range, the reader will send a command to the RFID card.

The RFID card receives the instruction, which will be stored in the chip information through the antenna sent to the reader.

After receiving the information, the reader will decode it and transmit it to the computer for processing.

The reading distance of an RFID card is affected by many factors, such as the size and power of the antenna and the frequency of the reader. Generally speaking, the reading distance is between a few centimeters and several meters. Since RFID cards use radio waves, care needs to be taken to avoid problems such as interference and signal eavesdropping during use.

The Unseen Enemy: Why ESD Safety is Paramount in Mobile Phone Repairing

Electrostatic Discharge;

In the intricate world of mobile phone repairing, where technicians delicately navigate microscopic components and complex circuitry, there's a silent, often invisible threat that can render even the most skilled hands useless: Electrostatic Discharge (ESD). While the focus is often on cracked screens, battery replacements, and software glitches, neglecting ESD safety can lead to catastrophic and latent damage to sensitive electronic components, resulting in costly rework, customer dissatisfaction, and ultimately, a tarnished reputation. For those seeking to build a successful career through a mobile phone repairing course in Calicut or a smart phone repairing course in Calicut, understanding and implementing robust ESD safety measures is not just best practice – it's a fundamental requirement.  

Modern smartphones are packed with incredibly sensitive integrated circuits (ICs) and microprocessors. These components are designed to operate with minute electrical signals, making them highly vulnerable to even the slightest electrostatic discharge. A static charge, imperceptible to human senses, can carry thousands of volts. When this charge finds a path to a sensitive component during the repair process, it can cause immediate and complete failure, or worse, create latent damage that manifests as intermittent faults or premature device failure days, weeks, or even months later. This can lead to frustrating troubleshooting, repeat repairs, and a loss of customer trust.  

Consider a technician working on replacing a faulty charging port. Without proper ESD precautions, the simple act of handling a circuit board or connecting a new component could inadvertently discharge static electricity built up in their body or tools. This discharge, even if unnoticed, can zap a tiny diode or IC on the motherboard, leading to a seemingly unrelated issue later on, such as power drain or Wi-Fi connectivity problems. Such hidden damage can be incredibly difficult to diagnose and repair, often leading to the conclusion that the device is beyond repair.  

For individuals and businesses offering mobile phone service course in Kozhikode or mobile phone repairing training Calicut, emphasizing ESD safety is crucial for producing competent and reliable technicians. A comprehensive training program should dedicate significant time to educating students on the principles of ESD, the types of damage it can cause, and the preventative measures that must be implemented in every repair scenario. This includes practical demonstrations and hands-on experience with ESD-safe workstations and equipment.

The cost of neglecting ESD safety far outweighs the investment in proper preventative measures. Implementing an ESD-safe environment involves several key elements:

ESD-Safe Workstations: These include grounded mats and wrist straps that dissipate static charges safely. Technicians should always use a properly grounded wrist strap connected to the workstation ground point while handling electronic components.  

ESD-Safe Tools: Specialized tools made from conductive materials help to prevent the buildup and discharge of static electricity. This includes tweezers, screwdrivers, and soldering irons.  

ESD-Safe Packaging and Handling: Components and circuit boards should be stored and transported in anti-static bags and containers. Direct handling of sensitive components should be minimized.  

Proper Grounding: Ensuring that all equipment, including soldering stations and diagnostic tools, is properly grounded is essential to create a safe working environment.

Humidity Control: Maintaining a certain level of humidity in the repair environment can help to reduce the buildup of static charges.  

Antistatic Sprays and Wipes: These can be used to neutralize static charges on surfaces and components.  

Employee Training: Regular and thorough training on ESD awareness and best practices is paramount. All technicians should understand the risks and the importance of adhering to safety protocols.

While the focus here is on mobile phone repair, the principles of ESD safety are equally vital in other electronics repair fields, such as laptop repair course in Kozhikode. The miniaturization of components across all modern electronic devices means they are all susceptible to ESD damage. Therefore, the foundational knowledge gained in a quality mobile phone repair course regarding ESD safety is directly transferable and highly valuable in the broader electronics repair industry.  

In conclusion, ESD safety is not a secondary consideration in mobile phone repairing; it is an integral part of the process. Ignoring it can lead to a cascade of problems, from immediate component failure to insidious latent damage that erodes customer trust and increases operational costs.

For aspiring technicians enrolled in a mobile phone repairing course in Calicut or a smart phone repairing course in Calicut, mastering ESD safety protocols is as crucial as learning to diagnose faults and replace components. It is the unseen shield that protects delicate electronics and ensures the longevity and reliability of repaired devices, ultimately contributing to a successful and sustainable repair business. Emphasizing and practicing rigorous ESD safety is the hallmark of a professional and trustworthy mobile phone repair service.   Sources and related content

The Buro: Owners of EU Microprocessor Plant Shipped Chips to Russia Despite Sanctions

Businessmen that own a plant in Latvia shipped microchips used to build drones to Russia despite Western sanctions in the wake of the Kremlin’s invasion of Ukraine.

When Russian troops poured over the border with Ukraine in early 2022, SMD Baltic, a Latvia-based microchip firm with a plant in the city of Daugavpils, publicly condemned the invasion and stated that it would no longer take orders from Russian or Belarussian firms. 

But in fact its Belarussian owners, Siarhei Khvalko, Maksim Bohush, Siarhei Sayavets, and Latvian citizen Dmitrijs Radkevičs, reportedly continued to export Western-made chips to Russia using a secretive network of companies, according to The Buro’s most recent investigation.

Prior to the invasion of Ukraine, the SMD Baltic plant shipped around half of its products, which included microchips and was worth almost $1.2 million in 2021, to a single Russian firm called Novaya Elektronnaya Kompaniya (NEK) and owned by the same three Belarusian businessmen.

By the time the EU and U.S. banned the sale of microchips to Russia in late 2022, NEK had devised new supply chains through Kazakhstan, Turkey, and China. The Russian firm imported $1.3 million worth of electronic components into Russia in 2023, among them chips made by U.S. firms — therefore subject to U.S. sanctions — Intel, Texas Instruments, and Analog Devices.

"Any goods with U.S. inputs (production machinery, intellectual property, components, etc.) falls under U.S. export controls no matter where they are manufactured," Benjamin Hilgenstock, a senior economist at the Kyiv School of Economics and a member of the international working group on sanctions against Russia, told The Buro.

Texas Instruments and Analog Devices told the outlet that they did not do business with the company mentioned above, which supplied American chips to Russia.  

In late 2023, the trio of businessmen sold NEK to Vitaly Privolnev, who had managed the firm since 2016. The Buro believes that the Privolnev is likely a front for the three original owners.

Through another firm registered in Minsk, called SkyGlobal, Khvalko reportedly supplied Russia with 230,000 Western made parts, worth $1.5 million. The recipient, a company called Bulat, is controlled by two U.S. sanctioned entities: Rostelecom and the Elvees Research and Production Center.

In 2021, SMD BY, another company owned by Khvalko, Bohush, Radkevičs and SMD Baltic manager Pāvels Levins, opened a manufacturing facility in a Belarussian business park to supply the Eurasian Economic Union with electronic circuit boards.

After renaming itself “Micromount” three months after the start of Russia’s invasion of Ukraine, the firm began selling semiconductors to Russian firm Kontraktika which is owned by an associate of theirs, Vital Khatsuk.

Khatsuk formerly worked for Alsochip, a Belarussian company owned by Khvalko and Bohush.

The Buro’s investigation also revealed that since 2023, one of Micromount’s biggest customers has been Geoscan, a Russian technology conglomerate based in St Petersburg, to which it sold over $1 million dollars worth of components. 

The United States sanctioned Geoscan for its role in producing drones for the Kremlin’s war effort. Innopraktika, a fund managed by Vladimir Putin’s youngest daughter, Katerina Tikhonova, owns a 10% stake in the group.

Micromount also sold electronic components to Reglab, part of the Prosoft-Sistemy group. Before the war, the latter enjoyed a close relationship with Uralvagonzavod, the world’s biggest tank manufacturer.

When The Buro presented to Khvalko, he told them that “[w]e don't work with anything related to war. This is our principled position.”

Although violating sanctions by shipping Western chips to Russia, Khvalko and his partners are thought to have made at least $2.5 million and the revenues of SkyGlobal and Micromount increased by factors of 70 and 12, respectively.

Main functions and maintenance methods of stepper motor drivers

1.Introduction to the working principle of stepper motor drivers The stepper motor driver is an actuator that converts electrical pulses into angular displacement. The stepper motor driver accurately controls the number of steps, speed and direction of the stepper motor by receiving pulse signals from the control system. The working principle of the stepper motor is to convert the electrical pulse signal into angular displacement, and control the angular displacement by controlling the number of pulses, thereby achieving precise control of the motor position.

2.Main components of stepper motor drivers ‌1.Microprocessor: As the core component of the stepper motor driver, it is responsible for receiving input signals, processing control algorithms and outputting control signals. Microprocessors usually use high-performance, low-power single-chip microcomputers or DSP chips, with rich peripheral interfaces and powerful processing capabilities. ‌2.Power amplifier: Responsible for amplifying the control signal output by the microprocessor into the driving current required by the motor. The power amplifier usually uses switching power supply technology, with the characteristics of high efficiency, high power density and low noise, and has over-current, over-voltage, short-circuit and other protection functions to ensure the safe and stable operation of the motor. ‌3.Drive circuit‌: The bridge connecting the microprocessor and the power amplifier is responsible for converting the control signal into a signal that the motor can recognize.

3.The main functions of the stepper motor driver 1.Pulse distribution‌: The stepper motor driver controls the movement of the motor by receiving the control signal and converting it into the drive signal of the motor. Specifically, the ring distributor in the driver receives the pulse signal, direction signal and offline signal, and accurately controls the transistor in the power amplifier to turn on according to the instruction of the pulse signal, so as to drive the coil of the stepper motor to be energized. ‌2.Power amplification‌: The stepper motor driver provides sufficient power to drive the motor by amplifying the motor drive signal to ensure that the motor can operate normally. The drive module amplifies the motor drive signal and provides sufficient power to the motor to ensure that the motor moves in the specified step length and direction. ‌3.Precision control‌: The stepper motor driver achieves precise control of the motor position and speed by accurately controlling the step angle of the motor. This precise control makes stepper motors widely used in CNC equipment. ‌4.Protection function‌: The stepper motor driver also has a variety of protection functions, such as undervoltage lockout, overtemperature protection, etc. These functions can improve the stability and safety of the system‌.

4.Maintenance methods of stepper motor drivers ‌1.Regular inspection and cleaning‌: Regularly check whether the connection wires, power cords and switch power cords of the stepper motor driver are broken, and ensure that all connections are firm and there is no short circuit. At the same time, keep the surface of the driver clean to avoid dust accumulation affecting the heat dissipation effect‌. ‌2.Power supply system inspection‌: Use a digital multimeter to check the connection wires of the driver power supply system terminals and the working voltage of the power supply system to ensure that the power supply system is normal, without voltage abnormalities or insufficient power supply‌. ‌3.Heat dissipation management‌: Check whether the heat dissipation setting is proper and ensure that the driver has enough heat dissipation space. You can add heat dissipation equipment such as fans or heat sinks, and ensure that the working environment temperature does not exceed the specified range‌. ‌4.Parameter setting check‌: Check whether the current setting of the driver is correct to ensure that it does not exceed the rated current of the motor. Adjust the pulse width and the maximum step rate of the motor to avoid problems such as inter-turn and lost steps when the motor moves‌. ‌5.Environmental management‌: The stepper motor driver should be stored in a clean, well-ventilated environment with an ambient temperature of -40 to 50°C and a relative humidity not exceeding 95%. Avoid contact with corrosive, flammable gases, oil mist, dust and other impurities. ‌6.Regular maintenance‌: Regularly check the various components of the driver, including power cord, fuse, enable signal line, etc., to ensure their normal operation. Replace severely worn parts such as bearings in a timely manner. ‌7.Troubleshooting‌: If the driver fails, determine whether it is a common fault such as overvoltage, undervoltage protection, overcurrent, overtemperature, etc. according to the indication of the LED or other methods, and refer to the instructions for use for corresponding processing.

Three Key Concepts to Quickly Understand PMOS in MOSFETs

To understand PMOS, we first need to know: what is MOS? MOS stands for Metal-Oxide-Semiconductor Field-Effect Transistor. As the name suggests, M stands for metal, O for oxide, and S for semiconductor. In summary, it is a type of semiconductor device that uses metal and oxide layers.

In electronic circuits, metals are used when conductivity is needed, and insulating materials are used when conductivity is not needed. So, how do we get something that can both conduct and not conduct electricity? The answer is semiconductors.

Today, we are discussing MOS, which is one type of semiconductor. MOS has semiconductor properties that allow it to conduct electricity at times and insulate at others, acting as a switch in the circuit. PMOS is a type of MOS distinguished from NMOS by the channel type.

PMOS Working Principle

（Electronic switch）

Since PMOS functions as a switch, we need to understand how it turns on and off. First, we need to know that PMOS has an n-type substrate and a p-type channel. The direction of the current is from the source to the drain, carried by the flow of holes.

（Low-Level Drive）

PMOS is a low-level drive circuit, meaning that when the gate-source voltage (Vgs) is below a certain value, it will turn on. This is suitable when the source is connected to VCC (high-side drive). On the other hand, when Vgs is greater than or equal to a certain value, PMOS will turn off. In this way, the gate voltage acts like an invisible hand that controls whether PMOS is on or off by controlling the voltage level, thereby forming or cutting off the current in the circuit. Isn't it fascinating?

Advantages of PMOS

As one of the key players in MOSFETs, PMOS has irreplaceable functions and advantages.

1、Low Noise: PMOS has lower noise than NMOS, making it suitable for use in analog circuits.

2、High Threshold Voltage: PMOS typically has a higher threshold voltage, providing strong interference resistance.

3、Low Power Consumption: In a static state, PMOS has low current loss.

Applications of PMOS in Different Industries

（Large electronic demand households）

Thanks to its advantages, PMOS has penetrated various industries, and you can find its presence in many devices you use every day. In terms of market applications, the number one sector is consumer electronics. Devices like smartphones and tablets, which you are likely familiar with, all feature PMOS. PMOS is mainly used in key components such as microprocessors, memory chips, and display driver circuits, helping these devices maintain long battery life.

The second sector is computer networks, including processors, memory, and routers. PMOS plays roles in data storage, logical computation, and signal regulation. Third on the list are network communications, industrial control, automotive electronics, and power equipment. The demand for MOSFETs in these industries is also high, especially in automotive electronics, which now rivals consumer electronics in MOSFET demand.

Future Development of PMOS

The future development of PMOS transistors will focus on improving performance, reducing power consumption, increasing integration, and expanding application areas. New materials, advanced manufacturing processes, 3D integration technologies, and integration with emerging technologies like artificial intelligence and quantum computing will be the main directions for PMOS development.
