Abstract
A motor vehicle includes a multiphase AC electric motor having a stator wound with a first stator winding set including three phases and a second stator winding set including three phases, the three phases of the first stator winding set and the three phases of the second stator winding set wound oppositely to one another in the stator. Additionally, the motor vehicle includes a source of stored electrical energy and an inverter coupled to the source of stored electrical energy and to the electric motor to provide switched electrical energy to the first stator winding set and the second stator winding set. In addition, the motor vehicle includes a driver configured to simultaneously switch a relatively high side of the inverter to a first phase of the first stator winding set and a relatively low side of the inverter to a corresponding first phase of the second stator winding set.
