  • Circuit arrangement
    Patent number: 8614865
    Abstract: The present invention concerns a circuit arrangement (1) for electrically coupling a direct-current source (2) to a direct-current load, including a first and a second current input node (11, 12) for receiving a direct current generated by the direct-current source, a first and a second current output node (21, 22) for the delivery of the generated direct current to the direct-current load, an isolating means (4) connected between the first current input node (11) and the first current output node (21) and/or the second current input node (12) and the second current output node (22) for interrupting the electrical connection between the respective nodes, and an auxiliary switching means (14) connected between the first current input node (11) and the second current input node (12) for short-circuiting of the first and second current input nodes (11, 12).
