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 ...

This air-conditioner (AC) power saver circuit can control the operation of two separate AC units, reducing energy consumption during preset periods and cutting overall load and electricity bills.

One method of controlling power to AC circuits uses a TRIAC to turn the power on and off at precisely timed intervals that are synchronized with the AC signal. This method is called AC phase control.

Abstract: To improve the power density and efficiency of starter-generators (SGs) for aircraft ac power systems, a hybrid excited SG (HESG) with an independent excitation flux circuit is presented in ...

When picking a switch to use in electrical design, many people believe they can use any switch, provided its current rating is more than the maximum load in the circuit. This, of course, isn’t true.
