摘　　要：本文分析了与滞环相结合的空间矢量PWM的基本控制原理,并将该方法应用到并联型有源电力滤波器的控制中.利用Matlab进行了仿真研究,结果表明有源滤波器在任一时刻输出的补偿电流均能实时地跟踪指令电流,有效减小电流补偿误差,达到消除非线性负载所引起的谐波电流对电网污染的目的.An analysis on the basic control principle of space vector PWM combined with hysteresis is made and a method is devised for implementing the control over the parallel active power filter （APF）. Results of simulation by means of Matlab show that the output compensation current given at any time can track the instruction current of the APF at real-time. Thus, the current compensation error can be reduced effectively. Consequently, the harmonic current pollution on the grid caused by nonlinear load is eliminated.
