This paper proposes a general design scheme of DC chopper power supply based on single-chip microcomputer control. Firstly, the working principle and control method of Buck type buck chopper DC chopper power supply are introduced. The DC source, control circuit, drive circuit and protection circuit are introduced. The design completed the design of the entire DC chopper circuit. A simulation model of Buck-type buck chopper DC chopper power supply circuit is established. Based on this, a detailed simulation analysis of the Buck circuit is carried out. The results show that the simulated waveform is consistent with the design results.
