A device for limiting of the holding current of a gate turn-off thyristor

摘要

it is a device to limit the haltestromes a gtos indicated.the device is part of a ansteuerschaltung on and off of the gtos and characterized by a transistor in the strompfad between the einschaltschaltung the ansteuerschaltung and either the gate or the cathode of the abschaltthyristors is switched, and the steuerele ktrode of knowledge with the cathode. the gate of the abschaltthyristors is connected.in the first case, it is preferably to a pnp transistor, and the second is an npn transistor.
