Abstract: The aim of this paper is to compare two approaches such as cascaded H-Bridge Inverter and second uses new Multi-level Scheme for pulse width modulated voltage source inverter. This paper describes the simulation of above mentioned modules in SIMULINK/MATLAB Software. Comparison is done in terms of Total Harmonic Distortion (THD) in output load voltage, active Power and reactive Power. Better THD along with larger active and reactive powers produced in second scheme as compares to a certain stages of the first scheme.
