A charge transfer system includes an on-board vehicle motor system and a plug in supply. The on-board vehicle motor system includes a first motor including a plurality of stator windings, a second motor including a plurality of stator windings, a first inverter having a plurality of switch legs, a second inverter having a plurality of switch legs, a controller, and an on-board power supply. The plug-in supply is connected between at least one switch leg of the first inverter and at least one switch leg of the second inverter.
