New Approaches for Harmonics Reduction in Solar Inverters

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. It is shown that THD produced in second scheme is better up to a certain stages of the first scheme.
