ABSTRACT:
A semiconductor switch device comprising: a semiconductor switch having at least one pair of control electrodes and at least one pair of main electrodes, the control electrodes being supplied with a control current while the semiconductor switch is maintained conductive between said main electrodes, and the main electrodes being serially inserted in a current path; and a transformer having a first conductor responding to a current passing said current path, a second winding connected to said control electrodes, a third winding producing a magnetomotive force reverse to that produced across said first conductor, and a fourth winding producing a control current to said control electrodes by induction from said third winding, the third winding being equipped with an electrical pulse applying means capable of causing said third winding to produce said reverse magnetomotive force.
