Abstract :
The characteristics of high power static induction thyristors have been analyzed and SIThs were fabricated using a segment structure. In the segment structure, it was found that the low ranch gate resistance is effective for weakening the current crowding during turn-off. As a result, 4.5 kV-1 kA SIThs from 70 mm φ pellets have been made on an experimental basis and evaluated
