【Abstract】 This paper discusses the problems of harmonic suppression and reactive power compensation, and analyses the LC passive filter. On this basis,a compound active filter is proposed. Its configuration and principle are presented. Practical application shows that this filter has good properties in filtering and compensation,and raises the power factor.更多还原
