Patent ID: 7990098

Claim:
An inverter system for use in a vehicle having a first energy source and a second energy source comprising: a six-phase motor having a first set of three-phase windings and a second set of three-phase windings; 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; a first inverter coupled to the first energy source and 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; a second inverter coupled to the second energy source and 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; and a controller coupled to the first inverter and the second inverter, the controller being configured to control the first inverter and the second inverter to achieve desired power flow between the first energy source, the second energy source, the six-phase motor, and the three-phase motor.
