Current Hysteresis PWM Rectifier System Based on Single-Chip

Jun Li

Abstract

According to the control requirement of three-phase high power factor rectifier,this paper designs three-phase PWM rectifier adopts hysteresis current control strategy.The system not only improves the high-frequency switching problem,but also makes lower dependence on the PI parameters of the outer-loop voltage regulator.Through the control of single-chip,it effective reduced design cost.
