Abstract
Systems and apparatus are provided for an inverter system for use in a vehicle. The inverter system comprises a six-phase motor having a first set of three-phase windings and a second set of three-phase windings and a three-phase motor having a third set of three-phase windings, wherein the third set of three-phase windings is coupled to the first set of three-phase windings and the second set of three-phase windings. The system further comprises a first energy source coupled to a first inverter adapted to drive the six-phase motor and the three-phase motor, wherein the first set of three-phase windings is coupled to the first inverter, and a second energy source coupled to a second inverter adapted to drive the six-phase motor and the three-phase motor, wherein the second set of three-phase windings is coupled to the second inverter. A controller is coupled to the first inverter and the second inverter.
