1.1 Working Principle of Switch Mode Power Supply

Switching power supply is a power supply device that controls energy transfer through electronic switching devices (such as transistors, MOSFET, etc.). Its basic working principle is to use high-frequency switching technology to convert the input alternating current (AC) or direct current (DC) into the required DC output voltage. Compared with traditional linear power supplies, switching power supplies have higher efficiency and smaller size.

The core components of switching power supply include switch tube, transformer, filter and control circuit. Through the fast switching action of the high-frequency switch tube, the input electric energy is converted and transmitted in the transformer. The control circuit is responsible for monitoring the output voltage and ensuring the stability of the output voltage by adjusting the switching frequency and duty cycle of the switch tube.
