Hybrid Symmetrical Cascaded Multilevel Inverter having reduced number of Switches and DC Sources

摘要

Research in several new topologies of Multilevel inverter (MLI) has been carried out rapidly day by day. Recently several topologies have been introduced achieving higher levels with reduced device couns and DC sources. In this paper a new hybrid symmetric MLI is proposed. This topology has reduced number of controlled switches, Dc sources and numbers of capacitors which are very less compared to all the conventional topologies existed before. It reduces cost, size, complexity and hence enhances inverter efficiency.
