Three-phase Voltage Source PWM Rectifier with LCL Filter
摘要
Abstract
Three-phase voltage source PWM rectifier can attenuate high frequency harmonics effectively with LCL filter which has a better performance in contrast with L filter under the same standards. In this paper, mathematical model of PWM rectifier with LCL filter was analyzed and dual closed-loop control structure of inner current loop and outer voltage loop was designed at first. Then the filter's different parameters were analyzed and designed based on the current harmonic restriction. At last, a prototype of 5kW rectifier was established for experiment. The results show that the rectifier could sinusoidal input currents and perform at high power factor.关键词
