“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 ...

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 ...

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.

Switching power supplies are also called switch-mode products or switching mode power supplies (SMPSs). Compared to linear power supplies, switching power supplies offer greater efficiencies and are ...

Switch mode transformers (switching transformers) are used mainly in switching power supplies and DC-DC converters. They provide a storage element for transferring energy from input to output in ...

GaN switches promise higher efficiency and higher power density in SMPS. This article discusses the readiness of this ...
