Patent ID: 7675191

Claim:
A device for feeding auxiliary operating facilities of a fuel-electrically driven vehicle with a combustion engine, with a generator driven by the combustion engine, with a rectifier connected with the generator on the AC voltage side and assigned to the generator, wherein the rectifier on the DC voltage side is connected with a first and a second connection of a DC voltage circuit assigned to the rectifier and connected downstream of the rectifier, wherein, a first and a second step-down converter each is connected with the first and second connection of the DC voltage circuit, and wherein the first step-down converter is connected to a first DC voltage rail system for the feeding of the auxiliary operating facilities assigned to the first step-down converter and connected downstream of the first step-down converter and the second step-down converter is connected to a second DC voltage rail system for the feeding of the auxiliary operating facilities assigned to the second step-down converter and connected downstream of the second step-down converter.
