Several multilevel inverters have been proposed and extensively studied. The main topologies are the neutral point clamped inverter, the flying capacitor inverter and the cascaded connection of bridge inverters. A modular recently proposed alternative is the dual inverter configuration. This topology requires only two classical three phase voltage source inverters. One of the characteristics of this...
A new hybrid multilevel inverter using a single DC source for open-end winding induction motor is proposed. This power converter uses one three phase bridge inverter and three single-phase inverters, while using only one DC source. Due to the topology and voltage values, this power converter works as three single-phase multilevel inverters. In order to maximize the inverter output voltage levels there...
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...
