1. A charge transfer system, comprising:

  • a plug-in power supply electrically connected between at least one of a first plurality of switch legs of a first inverter and at least one of a second plurality of switch legs of a second inverter, the plug-in power supply including a charge port; and

    a controller operatively coupled to the first inverter and the second inverter, wherein the controller selectively modulates at least one of the first plurality of switch legs of the first inverter or at least one of the second plurality of switch legs of the second inverter such that electric current flows from an on-board vehicle power supply through at least one of a first plurality of stator windings of a first motor or at least one of a second plurality of stator windings of a second motor to the plug-in power supply for output at the charge port, and wherein the controller further selectively modulates the plurality of switch legs of the first inverter that are not directly connected to the plug-in power supply and the plurality of switch legs of the second inverter that are not directly connected to the plug-in power supply to reduce common mode noise between the plug-in supply and the on-board vehicle power supply.
