Abstract: This paper presents the performance evaluation of a hybrid power filter for current harmonic elimination and improved input power factor. Hybrid filter consists of an active power filter and passive filters. In the proposed scheme shunt active power filter operates at very low frequency to achieve lower switching frequency and hence higher conversion efficiency. The combined operation of shunt active power filter and passive filter ensure THD of source current within the permissible limits set by various regulatory agencies and near unity supply power factor. The effectiveness of the hybrid filter has been verified by the extensive simulation results carried out in MATLAB/Simulink and SimPower systems software.

Keywords: hybrid filter; THD; active power filter; APF; conversion efficiency; hysteresis controller.
