三相有源滤波器模型，matlab环境下搭建，滤波效果良好，且在负荷变化时能够迅速跟踪谐波电流变化并进行补偿。-Three-phase active filter model, matlab environment to build, the filtering effect is good, and when the load changes can be quickly tracked changes and harmonic current compensation.

一个简化的有源滤波器串联配置。串联型有源滤波器的作用不是直接补偿谐波，但提高并联型无源滤波器的滤波。-A simplified active filter in series configuration. Action series active harmonic filters are not directly compensated, but to improve the shunt passive filter filtering.

有源滤波器补偿电流谐波检测算法PQ和IP/IQ法，simulink搭建模型并且误差极小-Active filter compensation current harmonic detection algorithm PQ and IP/IQ method, simulink build model and the error is minimal
