Classification: CPC H  B | IPC H

Claim 15:
16. A method of operating an electric drive unit including a stator, at least a first rotor including first rotor windings, and a low voltage inverter electrically connected with the first rotor windings, the method comprising:
producing a stator magnetic field via a high voltage inverter, and
using the low voltage inverter to produce an electric current in the first rotor windings to produce a first rotor magnetic field,
wherein the stator magnetic field interacts with the first rotor magnetic field to exert a torque on the first rotor, and wherein a maximum operating voltage of the high voltage inverter is greater than a maximum operating voltage of the low voltage inverter.
