Abstract: An electric powertrain (12) includes an engine (44) configured to provide mechanical energy and a generator (46) operably coupled to the engine and configured to convert at least a portion of the mechanical energy into electric energy. The electric powertrain further includes at least one electric motor (48) operably coupled to the generator, a plurality of driving members (34, 36), and at least one power electronics unit (50, 60) configured to control at least one of the engine and the generator. The at least one electric motor is configured to provide torque for the plurality of driving members.
