摘　　要：提出一种采用特定消谐脉宽调制的三相并联型有源电力滤波器谐波和无功电流的简单获取方法，并给出了主要单元电路结构图。仿真分析和实验结果证明这种电流指令信号获取方法是有效的。A simple harmonic and reactive current measuring method using SHE-PWM for three-phase shunt activepower filter is proposed in this paper. The structure of basic circuit is given. The method only uses three analog multipliersand the circuit is easy to be adjusted. It can also be used in static var compensator. The simulation and experimental resultsdemonstrate the validity of the proposed methed.
