本文阐述了PWM整流器发展过程、发展现状以及发展方向，分析了PWM整流器的基本工作原理及其分类，然后采用LabVIEW-Multisim协同仿真对AC-DC变换进行完整系统的闭环仿真，结合脉冲宽度调制(PWM)信号的控制策略对整流器进行控制，最后对仿真结果进行分析。-This paper describes the development of PWM rectifier produced and present domestic and foreign research hot topic,

matlab仿真有源滤波器，三相电源输入，树春进行了PWM调节，可以调试输出正确波形，有不错的仿真价值-Active filter, can output waveform correctly, three-phase power input and output using the PWM controller for adjustment, waveform is correct, is more accurate
