The field of engineering that deals with the design and analysis of power conversion circuits and devices is called power electronics, although power supply design is a true cross-disciplinary task.

Editor's note: Designers at all levels of power management design will find this application article both educational for those not very familiar with these basic concepts as well as an excellent ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

This file type includes high resolution graphics and schematics when applicable. Switching power supplies are inevitable in today’s designs. They’re power-efficient and thermal-efficient, with various ...

The flyback design is a switched-mode power supply (SMPS) that’s been used for 70+ years and still going strong. This supply—also called a power converter—has two distinct operating phases, with power ...
