The application of shunt active filters for the harmonic and reactive power compensation in the high power range is mainly restricted because of their low efficiency and the high cost of inverters with high switching frequency. Moreover, the compensation effect is completely lost in case of internal fault in active filter. Hybrid active filters as the combination of a low power PWM inverter and passive filters have been researched and developed to overcme the limitations of shunt active filter. However, they do not have control over fundamental reactive power. This paper proposes a new hybrid active compensator for harmonic and fundamental reactive current compensation, which consists of two small-rated active filters and one bank of passive filters. Simulation and experimental results are presented to show the advantages of the proposed compensator topology.
