The conventional inverters have the drawbacks of Harmonics as well as Total Harmonics Distortion (THD). Modeling and Simulation of Cascaded H-bridge multilevel inverters of different levels are design in this paper. Cascaded H-Bridge Multilevel Inverter contain less number of switches and produce lesser harmonics in the output voltage. The harmonics and THD at the output of cascaded h-bridge inverter of different levels such as five level, seven level, nine level and eleven level are studied and compared. Cascaded H-Bridge Multilevel Inverter topologies are very popular in power conversion systems for high power and power quality demanding applications.
