Design of intelligent switching power supply based on DSC control

Abstract

This article introduced a digital switching power supply system based on the DSC control, focuses on the control unit of the digital power system and software function realization. The main circuit of power system uses the isolated-type Half-Bridge topology. The processor of control unit selects TI, PICCOLO Series DSC chip, and the model is TMS320F28023. This system software uses the voltage closed-loop control method and the PID algorithm governing system output. This digital switching power supply system's output voltage and maximum output current can nimble adjustable. This system has many features, such as fast response, low ripple factor, remote communications and intelligence protection. It has very good application value.
