AN ZIG-ZAG CONCATED DOUBLE RUNG H-BRIDGES BASED MULTILEVEL VOLTAGE SOURCE INVERTER STRUCTURE

Abstract

These instructions give This paper suggests a newer multilevel inverter (MLI) with lessened number of switches (hence gate drivers) and active devices in conduction path. The key philosophy imbibes that the structure constituted using series connected twin sourced half bridge power modules. Each power module composed of two isolated dc sources/capacitors and six switches. The proposed topology makes use of few modules with reduced number of components for a specific level of output voltage as compared to cascaded H- Bridge inverter. The proposed Zig-Zag Concatenated Double Rung H-Bridges Based MLI (ZCDRHBMLI) is thoroughly investigated in MATLAB/Simulink based simulation and the performance adequately validated through experimental results. Thus, this contribution clues the emergence of a new variety of MLI and brings a different dimension in power control applications.
