Circuit arrangement for controlling a plurality of semiconductor switches connected in parallel

A circuit arrangement (200, 200′) for controlling a plurality of semiconductor switches (120) connected in parallel, the circuit arrangement comprising:

• a switch-on terminal (213),
• a switch-off terminal (214),
• a plurality of control terminals (220), which are each provided for connection to a control terminal (123) of one of the plurality of semiconductor switches (120),
• wherein the switch-on terminal (213) and the switch-off terminal (214) are each connected to each of the plurality of control terminals (220), and
• wherein a switch disconnector (230) is provided between the switch-on terminal (213) and at least one of the control terminals (220), and wherein a potential of the switch-on terminal (213) is switchable,
• further comprising
• at least one detection and control arrangement (260, 280) has a detection unit (280) and a control unit (260), which is designed to detect a current flow into the at least one of the control terminals (220) and, when a short circuit is identified from the current flow, to control the switch disconnector (230) causing it to open, wherein the detection unit (280) includes a low-pass filter, and
• a diode (235) provided between the switch-off terminal (214) and the at least one of the control terminals (220), the diode (235) having its forward direction in the direction of the switch-off terminal (214), and the diode connected to the switch-off terminal (214) and a switch-off resistor, the switch-off resistor provided between the switch-off terminal (214) and the at least one of the control terminals (220).
