Abstract

In this paper, a novel multilevel electrolytic capacitor-less inverter is proposed. With the three-winding coupled inductor, input voltage can be divided without electrolytic capacitors. Hence, no voltage-balancing circuit is needed. Less power switches are required for the proposed circuit compared to the existing topologies. Only ten switches are required to generate seven-level output. Finally, a laboratory prototype of seven-level inverter with 320V input voltage and 220 Vrms/3kW output is implemented. The efficiency under full load is 94.82%, the maximum efficiency is 96.39% under 74.34 % load. Extended circuit is also proposed.
