The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

Inside nearly every electronic device is a simple coil of wire doing a powerful job—it’s called an inductor. Though small and ...

Download this article in PDF format. It’s now common to see circuit boards that carry hundreds of amps, especially in intensive data-processing applications, electric vehicles, and ac distribution.

There’s a small, silent component hiding in almost every electronic device—from your phone and laptop to your TV and charger.

Single-phase and 3-phase AC squirrel cage induction motors need some type of control circuit to initiate a start or stop function. The two types of ladder control circuits commonly used are the 2-wire ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

If you got your start in electronics sometime after 1980 your first project might well have been to light up an LED. Microcontroller projects often light up an LED, too, and a blinking LED is ...

Offline power supplies that drive loads of 200W and more require inrush-current limiters. Unrestricted inrush currents can reach hundreds of amperes, which may damage the line rectifier, open the fuse ...
