Several Common Switching Power Supply Working Principle

Switching power supply is simply a small transformer that converts AC voltage into DC voltage, Also known as switching power supply, switching converter, is a high-frequency electrical energy conversion device, is a power supply.

Its function is to convert a level voltage into a DC voltage containing a certain pulsating component after being rectified and filtered by a rectifier circuit and a filter circuit, and the voltage is converted into a square wave of the required voltage value by the high-frequency converter, and finally the square wave voltage is converted into the required DC voltage by the rectification and filtering.
