Title:
RAIL VEHICLE CIRCUIT ARRANGEMENT
Document Type and Number:
WIPO Patent Application WO/2013/171186
Kind Code:
A3
Abstract:
The invention relates to a rail vehicle circuit arrangement, having at least one transformer (20) which, in a first operating mode, is electrically connected to a drive unit (28) and to a railway power supply system (12), and in a second operating mode is disconnected from the railway power supply system (12), and an intermediate circuit (26) which is connected between the transformer (20) and the drive unit (28). In order to make available a rail vehicle circuit arrangement of the generic type by means of which an advantageous reduction in the switch-on current surges can be achieved in a structurally simple way, it is proposed that the rail vehicle circuit arrangement has an auxiliary supply device (42) which is provided for feeding electrical energy (EA) into the intermediate circuit (26) in the second operating mode, and a pre-energization unit (43) which during operation draws the electrical energy of the intermediate circuit (26) in order to pre-energize the transformer (20).
