Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

While maximizing power efficiency at full-load is a top priority in the design of an AC/DC supply, standby power considerations and new power-efficiency standards loom larger. Thus, apart from the ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

The convergence of information technology (IT) equipment and telecommunications networks has brought about the need to power equipment with a variety of input requirements. Designers of today's ...
