Claim 2:
3. A traction drive system for a vehicle comprising:
a permanent magnet synchronous electric machine including a first winding system and a second winding system,
a first converter connected to the first winding system,
a second converter connected to the second winding system, and
a control device configured to (i) operate the first converter with block commutation and (ii) operate the second converter with pulse width modulation,
wherein the electric machine comprises a stator having a plurality of slots, each slot having two radial positions in which phase conductors of the first winding system and the second winding system are arranged,
wherein a first phase conductor of the first winding system is arranged in a different radial position in a first slot than in a second slot,
wherein the first winding system and the second winding system are connected in antiparallel, and
wherein the first phase conductor of the first winding system and a second phase conductor of the second winding system are controlled in antiphase, such that currents having opposite current directions flow in the first phase conductor and the second phase conductor.
