PERFORMANCE ANALYSIS OF SYMMETRICAL AND ASYMMETRICAL CASCADED H BRIDGE INVERTER

Abstract

This paper presents the comparative analysis report based on the conventional cascaded H-bridge inverter with equal DC sources (symmetric) and the proposed cascaded H-bridge inverter with unequal DC sources (asymmetric). This paper also analyzes the restriction on selecting unequal DC sources. It is shown that the proposed scheme provides the more number of voltage levels with the same number of switches as in conventional cascaded multi level inverter.
