High Performance Seven Level Active Shunt Filter for Harmonic Mitigation
نویسنده
چکیده
This paper deals with the simulation of a shunt active filter using seven level cascaded H-bridge multilevel inverter. The proposed active filter topology can also produce seven voltage levels, which significantly reduces the switching current ripple and the size of passive components. The seven level active shunt filter provides compensation of load power factor and current harmonics. For compensation current extraction, synchronous detection method has been used. The harmonic reduction is achieved in source currents as well as source voltages. Circuit model is developed and the same is used for simulation studies. The effectiveness of the proposed control technique is verified by the simulation results.
