1. A system for providing operating current supply and charging current supply in different modes of operation, comprising:

  • an electric machine including a rotor and a stator having stator windings,at least one charge storage device including charge storage device terminals,an inverter disposed between the charge storage device terminals and the electric machine, the inverter including a plurality of inverter phases, anda contact arrangement disposed so as to modify electrical interconnections between the inverter and the stator windings,wherein the contact arrangement is controllable so that each inverter phase is electrically interconnected with a stator winding set having windings separated from each other by a plurality of stator windings in other winding sets in a supply mode for driving the rotor of the electrical machine, and so that each inverter phase is electrically interconnected with a stator winding set having windings that are directly adjacent to each other and are not separated from each other in a charge mode for receiving current supplied from an external source through the stator windings and charging the charge storage device through the inverter.
