Abstract :
This paper analyzes and compares two approaches for dc to ac power conversion. First approach uses cascaded H-Bridge Inverter and second uses new Multi-level Scheme having Level Modules and H-Bridge. The simulation is done in SIMULINK/ MATLAB Software. The Total Harmonic Distortion in output load voltage, active Power and reactive Power produced by both the approaches are compared. It is shown that THD produced in second scheme is better up to a certain stages of the first scheme. And the available active and reactive powers are larger for the second scheme.
