ABSTRACT:
A circuit arrangement for retaining a main transistor in a conductive state while receiving an external turn-on control signal and bringing the main transistor to a complete cut-off state in response to an external turn-off control signal includes a circuit provided on the primary side of a transformer for supplying a turn-on signal or turn-off signal to the main transistor in response to the turn-on or turn-off control signal and a constant current circuit for maintaining the transformer primary current constant so that the currents derived from the turn-on and turn-off signals are kept constant.
