The basic understanding of the switching regulator circuit

Among various DC voltage regulator circuits, switching regulator circuits are the most widely used. Most color TV sets, some black and white TV sets, many video recorders, and computers are all switching regulator circuits.

This paper mainly explains the overview of switching regulator circuit and the working principle of switching regulator power supply.

Attached are several examples of switching power supply circuits, circuit details and more can be found in the PDF document!
