A Comparative Study of Multilevel Inverter Typologies with Reduced Switches

Abstract

From the past couple of decades, Multilevel inverter (MLI) technologies are suitable for high power industrial applications. Multilevel inverter (MLI) synthesizes several DC sources. Multilevel inverter (MLI) are the most suitable technology for conversion in renewable sources. This paper presents a new Multilevel inverter topology and a comparative study of Multilevel inverter (MLI) topologies in terms of number of switches, hormonic content and efficiency. These topologies are cost effective as compare to conventional Multilevel inverters (MLI). Despite of many advantages, multilevel inverter (MLI) with reduced switches basis some advantages like the voltage stress on the individual switches increases. For that, it is recommended to use switches of high rated values. All the topologies are modelled using Matlab/Simulink and the results are validated and compared.
