Abstract

This work presents a novel five-level hybrid Half-Bridge/ANPC multilevel inverter. Along with the switching states possibilities, employed modulation techniques, conduction losses analysis, and simulation results from a three-phase topology, it is presented the experimental results from a monophasic structure, operating with 1020Hz switching frequency, output frequency of 60Hz, phase output voltage of 220Vrms, output power of 2.3kW and power factor of 0.92. From the presented results, it can be noticed the reduced losses and better harmonic content.
