  • Device for short-circuiting two electric lines for reducing a voltage differential
    Patent number: 7199990
    Abstract: A device is for short-circuiting a first electric line with a second electric line in order to reduce a voltage differential. At least one first electronic switching device is provided between the first and second lines and at least one second electronic switching device is arranged anti-parallel to the first switching device. No mechanical switch is present for the direct short-circuiting operation.

  • Short-circuiting device
    Patent number: 6707171
    Abstract: In a device for the short-circuiting of a first electrical line (1) with a second electrical line (2) by at least one mechanical switching device (SM), at least one first electronic switching device (SE1) is arranged in parallel with the mechanical switching device (SM) and at least one second electronic switching device (SE2) is arranged reverse-connected in parallel with said first electronic switching device, by means of which a voltage difference that occurs between the first electrical line (1) and the second electrical line (2) can be bridged. Such a device is constructed in a simple manner and has short response times.
