Control device of semiconductor power device

摘要

A control device for controlling a double gate semiconductor device having a second gate electrode for controlling transition from a thyristor operation to a transistor operation, and a first gate electrode for controlling transition from transistor operation to an ON/OFF operation, and for controlling a current passing from a collector electrode to an emitter electrode, includes a first gate control circuit for delaying a turn-off signal to the double gate semiconductor device and applying the turn-off signal to the first gate electrode.
