I am Kevin Chen, I graduated from University of Electronic Science and Technology of China in 2000. I am an electrical and electronic engineer with 23 years of experience, in charge of writting content for ICRFQ. I am willing use my experiences to create reliable and necessary electronic information to help our readers. We welcome readers to engage with us on various topics related to electronics such as IC chips, capacitors, resistors, inductors, circuit breakers, diode, transistor, module, relay, opticalcoupler, connectors, PCBs, etc. Please feel free to share your thoughts and questions on these subjects with us. We look forward to hearing from you!
A microprocessor is the most used and most important component in any computer. It’s easy to say that computers would not exist without them. It’s also easy to say that we’re living in a world where most of us don’t even know what a microprocessor is. In this comprehensive guide, I will strive to satisfy…
Because circuits feature several power rails with stringent individual specifications and mandatory relationships, the power management IC (PMIC) is often critical for the lower-voltage DC subsystem. Creating required low-voltage DC rails using DC/DC converters or regulators is one thing, but many systems designs also require managing these power rails. This is becoming more common as…
LEDs are one of the most energy-efficient and long-lasting lighting technologies. They can be used for both indoor and outdoor applications, but they require a specific driver to function. LED drivers are considered the backbone of LED lighting systems. They help to control the current and voltage supplied to LEDs, which allow them to emit…
Thyristors are a fascinating semiconductor device class. They have features similar to diodes and transistors, which are silicon-based solid-state components. As a result, it may be difficult to identify thyristors from diodes and transistors. There are several distinct varieties of thyristors on the market to make matters more complicated. In some cases, the only thing…
What comes into your mind when you hear the word ‘instrument?’ The first thing that you will think of is the measurements. This is because most instruments are used for measuring the value of something. When it comes to transformers, you need to know that they are used in almost all electrical devices and electric…
Electrical conduits are important when it comes to installing electrical wiring. They provide the necessary support for the wiring and make it possible for someone to install or replace a wire without having to cut through drywall, etc. There are many different types of conduits, so before you decide which one is right for your…
With all of the gadgets and technologies that many of us use, it’s no surprise that more electric plugs will be required over time. As a result, many people turn to various possibilities to offer them more outlets. If you’re looking for these extra outlets, you might be confused about the difference between power strips…
Large oil-immersed transformers have a cylindrical device that sits between the conservatory and the main tank. A cylindrical object that looks like a solenoid valve is known as a Buchholz relay. All oil-immersed transformers with a rating of more than 500 kVA have it. This article will show you how a Buchholz relay works, how…
The fundamental reason that all AC sources (transformers or alternators) are rated in VA (or KVA or MVA) is that the load attached determines the current power factor. Because the load power factor is unknown (during the transformer manufacturing process), they are rated for resistive loads (PF = 1). Furthermore, why are transformers rated in…
You may not know about residual current devices(RCDs), but these devices are important for protecting you and your family from electric shock. There are different types of RCDs on the market, each with its benefits. So which one should you buy? And how do they work? This article offers everything you need to know about…
