Keep in mind when reading any article about electrical theory or application that it only scratches the surface of the topic. You can dedicate years of your life to understanding electrical theory and ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Three-phase is a common method of electric power transmission. It is a type of polyphase system used to power motors and many other devices. Three phase has properties that make it very desirable in ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

Welcome to my first blog post that explores fundamental principles of electrical engineering and attempts to tease out some new insights. For many of you, this will be a refresh of concepts you ...

Single-phase power supplies have been a power industry norm for ESPs for more than 60 years. Analog automatic voltage control and silicon-controlled rectifiers were the single-phase design standard ...

Researchers have clarified the mechanisms by which energy loss is locally maximized at a certain rotational speed in ...

In a power-supply topology for a computer system with a 12-V input and a 1-V, 20-A output, currents are high enough that duplicate power stages can be used to reduce stress and spread the thermal ...

In the emerging Internet of Things (IoT) market, powerline communication (PLC) is one of the preferred connectivity solutions for transferring data between devices. Using the omnipresent power line ...

Pingshan Phase II, a cutting-edge 1.35-GW ultrasupercritical coal-fired unit, achieves a remarkable net efficiency of 49.37%—making it the world’s most efficient coal-fired power plant. The ...
