ABSTRACT:
In a circuit arrangement for feeding electrical users with a DC voltage, a control circuit of a first switch controller serves as a current/voltage converter supplied from an auxiliary voltage source. Given such circuit arrangements, the auxiliary voltages should be generated with the simplest possible means and should be available as quickly as possible upon turn-on. For this purpose, the auxiliary voltage source is formed by a second switch controller whose switch element is parallel to an input of the first switch controller to which a capacitor is connected via a diode. Furthermore, the first and second switch controllers are positioned in series with one another at the input. The circuit arrangement can be advantageously employed in intermediate stations of communication transmission devices having DC current series feed.
