Large power supplies that operatefrom ac wall voltage havelarge input-filter capacitors. You mustlimit the inrush current to those capacitors.Otherwise, the supply may tripthe ac circuit breaker, or ...

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 ...

Thyristors, three-terminal electronic components with bistable behavior, are used in switching and power control circuits, both in DC and AC regimes. Thyristors are three-terminal electronic ...

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 ...

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 ...

ROHM leverages its LogiCoA technology to control a power-factor-correction stage and flyback DC-DC converter stage at the same time.

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.

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 ...

Part 4 focuses on testing for a reflow oven and build of a mixed SMT/through-hole board. This column will address reflow-oven temperature testing. It uses the lab equipment to build the circuit board ...
