Abstract

The invention relates to a device for supplying electrical energy to rail vehicles. An alternating-current supply (1) is thus connected to a rectifier (3a ). A connection (4) for a rail vehicle is arranged after the rectifier (3a). Several rectifiers (3) are arranged in parallel to the one rectifier (3a). A connection (4) for a rail vehicle is arranged after each rectifier (3, 3a). The rectifiers (3, 3a) are, for example, individually controllable.

Claims

1. A device for supplying rail vehicles with electrical power, having an AC voltage source (1) to which a rectifier (3) is connected, with the rectifier (3a) being followed by a connection (4) for a rail vehicle,

characterized in that a number of rectifiers (3) are arranged in parallel with the one rectifier (3a), and in that each rectifier (3, 3a) is in each case followed by one connection (4) for only one rail vehicle.

2. The device as claimed in claim 1,

characterized in that the rectifiers (3, 3a) can be regulated individually.

3. The device as claimed in claim 2,

characterized in that the DC voltage can be regulated up and/or down in the form of a ramp by the rectifiers (3, 3a).
