This paper presents a nine-leg (9 L) multilevel inverter to drive an asymmetrical six-phase induction machine in an open-end winding (OEW) configuration. The system is based on three conventional two-level three-phase voltage source inverters (VSIs) with three, two, or one isolated dc links. A machi...
