Performance evaluation of Symmetrical and Asymmetrical Cascaded H Bridge Multilevel Inverter Topology

Abstract

This paper reviews study of symmetrical and asymmetrical cascaded H-bridge multilevel inverter. Here symmetrical, binary asymmetrical and ternary asymmetrical structure formed by cascading two H-bridge cells are compared in order to find an optimum arrangement with high quality output voltage. Performance of these structures is verified through computer simulation using MATLAB/Simulink.
