Abstract

PURPOSE: To effectively prevnet the simultaneous conduction of a switching transistor, by connecting a simultaneous conduction preventive means.
CONSTITUTION: When a switching transistor 7 is in ON, the base potential of a PNP transistor 4 forming a simultaneous conduction preventive means lowers, a portion between a base and an emitter is forwardly biased, the PNP transistor 4 is in ON, NPN transistor 8 also is in ON, a portion between a base and an emitter of a switching transistor 6 is short-circuited and the switching transistor 6 does not conduct even if bias voltage is applied.
