摘　　要：分析了注入式混合型有源电力滤波器的工作原理,从几种常见的输出滤波器的传递函数出发,利用MATLAB建立输出滤波器参数的波动对补偿性能影响的仿真模型,发现LRC型输出滤波器在较低的开关频率下,获得比LCL和LC滤波器更优异的性能。综合考虑,选取了LRC型滤波器进行设计,最后利用PSIM建立装有LRC型输出滤波器的注入式混合型有源电力滤波器仿真模型。仿真结果表明:对于注入式混合型有源电力滤波器采用LRC型输出滤波器有很好的滤波效果。The working principle of the injection hybrid active power filter （APF） is analyzed. Based on several transfer functions of the output filter, the MATLAB was used to construct the simulation model to calculate the influence of output filter parameter fluctuations on the compensation performance. It is found out that the performance of the LRC-type output filter under lower switching frequencies is superior to that of the LCL and LC ty-pe filters. Therefore, the LRC-type filter was selected for design. Finally, the PSIM was used to establish the injection hybrid APF simulation model with LRC-type output filter installed. Simulation results show that the injection hybrid APF which adopts the LRC-type output filter has good filtering performance.
