Abstract
The present disclosure provides a control method for an AC-DC conversion circuit. The method includes: calculating working information of an AC-DC conversion circuit according to at least one circuit parameter information of an input voltage, an input current, an output voltage, and an output current of the AC-DC conversion circuit; comparing the working information of the AC-DC conversion circuit with a preset working range to obtain an actual switching frequency or an actual switching period of the AC-DC conversion circuit. The AC-DC conversion circuit can meet requirements of Total Harmonic Distortion (THD), Power Factor (PF), efficiency and Electromagnetic Interference (EMI) and the like by adjusting the working information of the AC-DC conversion circuit through the preset working range.
