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 ...

Here is a simple 12 volts DC to AC inverter circuit. This 120V AC power source is built with a simple 120V:24V or 110V:24V center-tapped control transformer and four additional component. This circuit ...

Power-control modules are circuits comprising devices such as silicon-controlled rectifiers, triacs, power transistors, and power rectifier diodes. Power-control modules are circuits comprising ...

Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

This course teaches how to design a feedback system to control a switching converter. The equivalent circuit models derived in the previous courses are extended to model small-signal ac variations.

A monolithic GaN mains power converter IC was the target of Leibniz University Hannover, which worked with Texas Instruments. And the result is a 15W off-line PSU that can feed a 30-60V LED string ...

Description: Introduction to power semiconductor devices, characteristics, and ratings. Emphasis on analysis and design of circuits with power semiconductors and associated devices. Power ...

Part 3 delves into critical equipment for testing today's electronics, and provides updates on circuit-board designs from Part 1. This series installment will address the lab equipment that’s pretty ...

More than 100 years after alternating current (AC) defeated direct current (DC) in the so-called Battle of Currents and became the standard way electricity was delivered, new technologies have opened ...
