| 摘要 |
The invention relates to a high-power switch (1) for interrupting DC circuits, comprising two current paths (2a, 2b) for high power, wherein at least two transistors (3, 4) connected in an anti-series manner in one of the current paths are provided in such a way that each transistor can block or enable exactly one of the two possible flow directions and at least one control (5) is provided for controlling the transistors. The aim of providing a high-power switch for bidirectionally interrupting DC circuits, which enables an interruption of the circuit for current flow in both possible current directions and also reduces the risk of remaining residual energy in the circuits, is achieved in that a connectable (6') ohmic resistor (R), by means of which the circuit can be short-circuited, is provided between the anti-serial transistors of the current path. |
