ABSTRACT:
A semiconductor switch device includes a semiconductor switch with a control electrode disposed serially in a power path connecting a DC power source and a load; a current transformer having a core and having a primary conductor for passing current in response to a turn-on of the semiconductor switch and a secondary winding connected to the control electrode of the semiconductor switch; and a magnetizing force applicator for magnetizing the core of the current transformer in the direction opposite to the magnetization generated by current flowing in the primary conductor.
