Hybrid power active filter - effectiveness of passive filter on the reduction of voltage and current distortion

Abstract

The purpose of this paper is to present a comparative studies of different circuit topologies of passive filter tuned to different series resonant frequency and also to show the influence of these topologies on the hybrid shunt active power filter effectiveness. The passive filter is an integral part of the hybrid shunt active power filter. This paper is mainly focused on the efficiency of the chosen hybrid power filter topology to reduce the level of current and voltage distortion at the point of its connection. Three comparison groups of passive filter are considered. The evaluation of the effectiveness is based on the simulation.
