The switching power supply is roughly composed of four parts: the main circuit, the control circuit, the detection circuit, and the auxiliary power supply. This time, I will introduce you to the first part: the main circuit.

Switching power supply is a high-frequency electric energy conversion device, which is a kind of power supply.

The following editor will introduce the working principle of pure sine wave inverter.

Pure sine wave inverter is an electric energy conversion device that converts direct current into alternating current. It completes the inverter task by turning on and off power semiconductor devices according to a specific law.

Modified sine wave inverter should avoid "inductive load".

In the inversion process of the modified sine wave inverter, the power loss of the system is greatly reduced due to the use of dedicated intelligent circuits and high-power field effect tubes.
