ABSTRACT:
The invention relates to a base control circuit for a switching transistor in which diodes are utilized to maintain the base-emitter voltage at a higher level than the collector-emitter voltage, upon the turn-on voltage being applied, to minimize switching-on losses while operating to avoid saturation.
