在整流器控制中,实际电流能否跟踪参考电流将影响整个系统的控制性能。通过分析整流器交流侧相量关系和电压空间矢量SVPWM基本原理,给出了基于SVPWM的电流控制方法,并运用MATLAB软件中的SIMULIK进行了仿真。结果表明,该控制方法具有良好的性能。

It will affect the control performance of three-phase rectifier whether actual current can track reference current well. By analyzing the vector of the rectifier and the basic principle of voltage space vector pulse width modulation（SVPWM）. The control method of three-phase voltage source rectifier（VSR） based on the SVPWM is proposed. The model is based on the SIMULINK environment of the MATLAB software＇. The simulating results show that this analysis and control method has good characteristic.
