Abstract

Multi-level converters have been used in several industrial applications. The following work seeks to present a novel power inverter structure featuring a low amount of devices for a multi-level converter with an asymmetric cascaded connection. The suggested architecture consists of a modified T-type structure and a half-bridge inverter that is back-to-back connected. The proposed circuit includes five dc voltage sources and nine semiconductor switches that generate 23 levels. To show the superiority of the proposed structure, a detailed comparison is made with other comparable multi-level converter structures. Simulations in MATLAB/Simulink are shown to validate the behaviour of the proposal.
