摘　　要：本文针对于常见的三相整流电路产生的谐波,设计一个基于三相电路的瞬时无功功率理论的并联型有源电力滤波器,检测部分是利用ip-iq法检测出谐波电流,通过电流指令计算机电路计算出需补偿的电流;运用基于空间矢量脉宽调制(SVPWM)技术作为控制方案,最后搭建MATLAB仿真模型,仿真结果表示,该方法可以有效检测谐波并有良好的谐波抑制和无功补偿效果。This paper focuses on the design of pcsive power filter and active power filter . A shunt active power filter based on the theory of instantaneous reactive power is designed, which is used to control the harmonics of three-phase rectifier circuit. Active Power Fi lter use the ip-iq method to detcurrents,and the command calculat ion circuk calculates the current to be compensated. The control scheme of shunt active power filter is based on space vector pulse width modulation （SVPWM） technique. Finally, using matlab simulat ion toolbox simul ink verifies the feasibil ity to the design.
