Abstract

This paper presents and studies a multilevel converter with two DC voltage sources and three H Bridges. The inverter modulates two independent single-phase voltages using a four wires output. The design of the inverter allows five levels to the modulated voltages that feed an asymmetrical two windings phase induction motor. The classical SPWM technique was used to modulate the multilevel power inverter switches; the frequency of the carrier (a triangular wave) was varied and total harmonic distortion (THD) of voltages and currents were compared. The simulation results were obtained using the Matlab/Simulink®/SimPowerSystems software.
