Abstract
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. The controller modulates the switch legs of the first and second inverters such that electric current flows through at least one stator winding of the first or second motor to charge the on-board power supply. The current flow can also alternate in phase with plug-in supply polarity to produce a stable stator flux vector angle preventing motor rotation during charge transfer.
