A New General Topology for Cascaded Multilevel Inverters with Increased Number of levels Based on Diagonal DC Source H-Bridge

This paper presents a new cascaded multilevel inverter topology in asymmetric configuration. Initially general topology is presented and then extended for higher number of stages. In this paper a new cascade diagonal dc source multilevel inverter topology is proposed, which included the increased number of output voltage levels with minimum number of switches as well as with minimum dc voltage sources. In this topology dc voltage sources connected diagonally across the switches, which allow series and parallel connection of dc sources to give the maximum output voltage levels with minimum number of dc sources. The proposed diagonal dc source multilevel inverter has been analyzed in asymmetric condition and it is verified by simulation results.
