Abstract

PURPOSE: To reduce a switching loss by flowing a reverse current to the bases of switching transistors in DC-DC converters and the like and shortening the switching time.
CONSTITUTION: The ON action of a switching transistor Q1 is performed by giving a base current thereto by the ON action of a driving transistor Q3. The OFF action of the switching transistor Q1 is performed by turning both driving transistors Q3 and Q4 ON simultaneously and by shorting both ends of the primary winding of a driving transformer T2, that is equivalent to the shorting of the base and emitter of the transistor Q1, therebt the base signal is reduced to zero and carriers are quickly discharged. The similar action is also performed when a switching transistor Q2 is OFF, thereby the collector current is quickly reduced to zero. In this constitution, the switching time is shortened and the switching loss is reduced.
