Abstract

PURPOSE: To increase the forward voltage change dv/dt quantity resistance of GTO (self-arc extinction type semidonductor element) by means of a simpleconstitution protection circuit and to apply a negative gate signal only during the period of the increase of the quantity increase. Thus, the loss of the gate circuit can be decreased.
