ABSTRACT:
A fuel/electric drive system having an internal combustion engine is disclosed, having a generator which is driven by the internal combustion engine and has a first stator winding set, having a first rectifier which is connected to the first stator winding set at the AC voltage end and to a first DC voltage circuit at the DC voltage end, and having a first inverter which is connected to the first DC voltage circuit at the DC voltage end and to a drive motor at the AC voltage end. In order to increase the robustness and availability of the fuel/electric drive system, the generator has a second stator winding set, with a second rectifier being connected to the second stator winding set at the AC voltage end and to a second DC voltage circuit at the DC voltage end, and a second inverter being connected to the second DC voltage circuit at the DC voltage end and to the drive motor at the AC voltage end.
