What is the principle of the FA1024 switch circuit?


The principle of the off circuit is to form an oscillation circuit consisting of a switch tube and a PWM (Pulse Width Modulation) control chip, generating high-frequency pulses. Convert the high-voltage DC generated by the high-voltage rectification and filtering circuit into high-frequency pulse DC, send it to the main transformer for voltage reduction, and convert it into low-frequency pulse DC.
