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.

This paper presents harmonic detecting method for a shunt hybrid active filter using adaptive filter. An adaptive noise canceling theory has been applied as a harmonic detection system to determine a harmonic reference signal for controlling

active filter shunt so good simpower system simulation
