A new general cascaded multilevel inverter using developed H-bridges is proposed. The proposed topology requires a lesser number of dc voltage sources and power switches and consists of lower blocking voltage on switches, which results in decreased complexity and total cost of the inverter. These abilities obtained within comparing the proposed topology with the conventional topologies from afo...

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 comp...
