摘要
A device and a method are disclosed for direct current voltage power supply to a traction system by means of converters from different alternating current or direct current voltages available on a power supply line. The power supply device is supplied with power by means of a first power supply element and a second power supply element connected to the power supply line. In this supply device the first power supply element is connected to the primary winding of the power supply transformer by a first connection element. The second power supply element is connected either to the power supply terminal of the traction system or to the mid-point of the series converters by a second connection element.
