As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

If you're seeking a way to measure current and power in a circuit, you need to know about current-sense amplifiers (CSAs). A CSA is a specialized op amp connected as differential amplifier with ...

Current is a measure of how much electric charge flows through a circuit. The more charge that flows, the bigger the current. Current is measured in amperes. The symbol for ampere is A. For example, ...

Here is a close look at the common- versus differential-mode voltage and instrumentation amplifier (IA) topologies.

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

In this first of a three-part series on power quality surveys, we take a look at the role of baseline surveys, the tools ...

The phrase power factor frequently is used in the electrical and power electronics industry. For example, home, office, and industrial electrical equipment often is fitted with power factor-corrected ...
