The increasing use of integrated circuits in modern electronic systems has resulted in a growing awareness about lightning overvoltage hazard. The integrated circuits, especially large-scale ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Abstract: Definite-purpose switching devices for use in metal-enclosed low-voltage power circuit breaker switchgear are covered in this standard. The switching devices are fused, drawout type, ...

Abstract: The following enclosed low-voltage ac power circuit breakers are covered in this standard: a) stationary or drawout type of two-, three-, or four-pole construction, with one or more rated ...

Apparent power vs real power explains the difference between total power in an AC circuit and the actual usable power. Understanding this relationship helps improve efficiency, correct power factor, ...

Calculations of power and energy are relatively straightforward when the subject is strictly dc circuits. The situation is more complex in the ac world, however. Here are the basics of watts and ...

Our fundamental passive and inherently analog components—resistors, capacitors, and inductors—are so conceptually simple and easy to describe that we often don’t fully articulate or appreciate the ...

This file type includes high-resolution graphics and schematics when applicable. Jerry Twomey, founder of Effective Electrons and CTO of WiPow Group If you’re bringing ac power directly into your new ...
