New Approaches for Harmonic Reduction Using Cascaded H-Bridge and Level Modules (140109)

DOI :

Abstract : This paper analyzes and compares two approaches for dc to ac power conversion i.e. inverter . First method uses cascaded H - Bridge Inverter and second uses new Multi - level Scheme having Level Modules and H - Bridge. The simulation is done in MATLAB Software. Also the hardware can be done by taking the AC supply from the mains and converts it into DC suppl y by using rectifier. MOSFET can be used for switching purpose. The Total Harmon ic Distortion in output load voltage,produced by both the approaches is compared. It is shown that THD produced in second scheme is better up to a certain stages of the first scheme. The Total Harmonic Distortion produced in output load voltage when casca ded H - Bridge is used is 12.64% while t he Total Harmonic Distortion produced in output load voltage when Level Modules and H - Bridge are used is 7.94%.
