Analysis of new H-bridge based cascaded multilevel inverter

This paper deals with the design and analysis of new h-bridge based single and three phase cascaded multilevel inverter. It has two types of sources: symmetric and asymmetric source. In this topology asymmetric source is preferred because it provides large number of output voltage level with minimum number of switches. This new H-bridge based cascaded multilevel inverter is able to increase output voltage levels with reduced number of power electronic device drive circuits, and DC voltage sources. In this paper generated 31 level output voltage and the main objective is to reduce harmonics with multilevel voltage without increasing number of switches this cascaded multilevel inverter is simulated using MATLAB /SIMULINK for single phase and three phase circuits.
