Abstract

A new power conversion structure for a three-phase multilevel inverter is proposed in this paper. This structure uses a LeBlanc transformer and three single-phase voltage source inverters. The power converter topology has two single-phase outputs that connect to the LeBlanc transformer. This transformer allows deriving two-phase voltage to a three-phase source. This multilevel power conversion structure allows obtaining a five-level three-phase inverter. To control the proposed converter a sliding mode controller with a vectorial modulator was used. Simulation results of the proposed converter structure with their control system are presented. From the obtained results it possible to confirm the voltage multilevel waveforms and the effectiveness of the proposed control system technique.
