The invention relates to a rectifier system (1) for a vehicle, in particular a railway vehicle that can be operated in a plurality of power supply systems, comprising: at least two DC voltage conductors (5, 6, 7) for providing DC voltage potentials, a plurality of grid rectifiers (8) for converting an input-side AC voltage into a DC voltage supply on the DC voltage conductors; a supply transformer (21), in particular a multiphase delta-star transformer, for generating an auxiliary supply voltage; a plurality of auxiliary rectifiers (20) for providing phase voltages for the supply transformer, a switching unit (11, 13) designed to apply an applied AC voltage to the grid rectifier (8) in a first operating mode and to apply an applied DC supply voltage to the DC voltage conductors (5, 6, 7) in a second operation mode; and a selector switch (22) for connecting at least one of the grid rectifiers (8) to the supply transformer (21) in the second operating mode, in order to apply to the supply transformer (21) a phase voltage generated in the at least one grid rectifier (8) from the DC supply voltage. The invention further relates to operating such a rectifier system (1). |
