Abstract:
1. A circuit arrangement for electrically coupling a direct-current source to a direct-current load, including a first and a second current input node for receiving a direct current generated by the direct-current source, a first and a second current output node for the delivery of the generated direct current to the direct-current load, an AC isolating switch connected between the first current input node and the first current output node and/or the second current input node and the second current output node for interrupting the electrical connection between the respective nodes when the AC isolating switch is opened, and an auxiliary switch connected between the first current input node and the second current input node for short-circuiting of the first and second current input nodes prior to opening the AC isolating switch, wherein the short-circuiting diverts the direct-current away from the AC isolating switch so that the AC isolating switch is opened while in a low current state.
