Abstract

PURPOSE: To reduce power loss thus to improve efficiency by overdriving transistor sufficiently to shorten rising time and supplying reverse-base current to shoten falling time.
CONSTITUTION: DC power source supplied on terminal 1 is turned on-off at switching transistor 8 by the signal from control circuit 11 and passed through smoothing circuit comprised of choke coil 14 and capacitor 7 to produce stabilized output voltage on output terminal 2. DC power source circuit 25 for bringing base voltage of transistor switching 8 lower than emitter voltage is provided to supply reverse base current thus to shorten rising time of switching transistor 8 and to reduce falling time.
