Abstract
A device for the feeding of auxiliary operating facilities for a fuel-electrically driven vehicle with a combustion engine is stated, which device comprises a generator driven by the combustion engine and a rectifier connected with a generator on the AC voltage side, wherein the rectifier on the DC voltage side is connected with a first and a second connection of a DC voltage circuit. Alternatively, first and second rectifiers connected with the generator on the AC voltage side can be provided, wherein the first rectifier is connected on the DC voltage side with a first and a second connection of a first DC voltage circuit and the second rectifier on the DC voltage side with a first and a second connection of a second DC voltage circuit. Saving of the space requirement and increase of the robustness and the susceptibility to faults is achieved in that a first and a second step-down converter each is connected with the first and second connection of the DC voltage circuit, and that the first and second step-down converter is connected with a common DC voltage rail system for the feeding of the auxiliary operating facilities. As an alternative to the second step-down converter a further-rectifier connected with the generator on the AC voltage side can also be provided wherein the first step-down converter and the further rectifier are then connected with the common DC voltage rail system for the feeding of the auxiliary operating facilities.
