Abstract: Power-electronics engineers designing switched mode power supplies (SMPS) are faced with the challenges of limited space, the need to meet worldwide energy regulations, and ease of design.

While he was fortunate enough that someone labeled it as having a bad power supply, things aren’t always that easy. He gives a broad explanation as to how switched mode power supplies work as ...

“They don’t build ’em like they used to.” There’s plenty of truth to that old saw, especially when a switch-mode power supply from the 1940s still works with its original part ...

The common type of power supply used with computers and other electronic equipment. The "switching" comes from switching a transistor on and off to create square waves for input to a transformer.
