摘　　要：针对三相电流型PWM整流器交流侧引入了LC滤波器而带来的超前功率因数问题,采用三值逻辑PWM信号发生技术进行脉宽调制,控制系统采用双闭环控制方式,在Matlab/Simulink环境下建立了该整流器的仿真模型。仿真结果表明,该调制方法和控制方式能实现电流型整流器的交流侧单位功率因数运行,并获得稳定的输出直流。Aiming at how to overcome the advanced power factor because of the introduced LC filter at the AC side of three-phase current source PWM rectifier,a tri-logic PWM technology and double closed-loop control method were used.The rectifier’s simulation model was established under Matlab/Simulink environment.The simulation results indicated that the current source rectifier＇s AC side could run at unity power factor and the rectifier could obtain stable output DC current.
