摘　　要：针对现存的混合型有源滤波器的无源滤波部分只是对1种谐波情况设计的、对变化的信号不能改变滤波形式、当电网波动时增加有源滤波部分的压力等问题,进行了改进。其创新点是引入可控可调式的补偿电路结构,可以针对变化的电网情况改变补偿的网络结构,而不是仅仅改变同一网络的参数,对电网达到跟踪补偿的效果。它对电网谐波污染和无功损耗均有很好的抑制和补偿作用,必定会在实际应用中得到广泛的发展。The reactive filter part of the existing mixture type active filter is designed only on 1 harmonic wave, which cant change the shape of the filtering wave pointing to the changed signals and increase the pressure of the active filtering part while the power network is under fluctuation. The new design corrects the previous shortcomings. The new points include introduction of controllable and adjustable compensation circuit, which can change the compensated network structures according to the change of the power network and trace the network change and compensate it. It has a good function of restrain and compensation to the harmonic wave pollution and reactive consumption, It will be widely used in practice.
