초록

A circuit is provided in which a voltage due to a minute current is applied to a gate terminal from a collector terminal when a collector voltage is higher than a gate voltage in an operation of current limitation. Thus, an increase in the collector voltage immediately after the operation of current limitation starts serves to boost the gate voltage. The boosted voltage suppress an abrupt increase in the collector voltage. When the collector voltage is reduced by oscillation, the action of boosting the gate voltage is lowered to suppress the reduction of...
