| 摘 要： | 电压型PWM整流器通过对整流器直流侧电压PWM调制，不但能使直流电压在一定范围内可调，而且使整流器的交流侧电流正弦化，并能够实现单位功率因数运行，实现高功率因数的整流装置．而控制PWM整流器交流侧的方法有多种，从电压型PWM整流器的静态模型入手，详细分析了电压型PWM整流器交流侧电流电流的控制规律，得出了一种间接电流控制模型，并阐述了间接电流控制的PWM整流器系统的设计，最后对该方法进行仿真，结果表明，采用这种电流控制，能够实现PWM整流器高功率因数运行．

| Abstract: | With pulse width modulation the PWM voltage source rectifier can not only adjust the DC voltage in certain range, but also make the current in AC side of the rectifier be sinusoid and creates rectifier with high power factor. The indirect current control is an easiest way to control the current in the AC side of the recitifier among many current control ways. The law of the indirect current control was discussed the PWM voltage source rectifier system was presented by indirect current the indirect current control can obtain the rectifier wich high power factor based on its static model. The design control. The simulation result shows that performance. |
