Abstract

In this paper, a 9-level symmetrical modified multi-level cascaded H-bridge inverter with reduced switch count is considered. The operation and control of 9-level inverter is discussed. This multi-level inverter uses four symmetrical DC input sources and twelve unidirectional power semiconductor switches. The basic operation with equal width modulation and resistive and Resistive-Inductive loads are verified with the help MATLAB simulation. The simulation outputs are presented and confirm the operation of nine level inverter operations. Together with the traditional topologies and some other inverters, this inverter topology is capable to produce more number of output voltage levels by means of less number of power switches and driver circuits. Simulation results confirm the probability of this inverter topology
