Claim 0:
1. 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, and wherein the first winding system and the second winding system are connected in antiparallel, and
wherein the first converter and the second converter comprise different semiconductor switches and the semiconductor switches have different switching states.
