An electric drive system includes an electric machine having a stator assembly and a rotor assembly. The stator assembly has a plurality of multi-phase stator windings, including a first stator winding and a second stator winding. A first inverter is adapted to feed the first stator winding. A second inverter is adapted to feed the second stator winding. The electric machine is a wound rotor machine, with a respective frequency of an alternating current (AC) in the rotor assembly being synchronized with the respective frequency of the AC in the stator assembly. The rotor assembly includes a multi-phase rotor windings. The electric machine is configured such that power transfer between the first stator winding and the second stator winding is achieved when the rotor assembly is stationary.
