Abstract

PURPOSE:To reduce switching loss by a method wherein a field-effect transistor for power is connected in parallel with a bipolar transistor for power. CONSTITUTION:Load 4 at an output terminal of a power source 3 and a parallel circuit of a bipolar transistor 1 for power and a field-effect transistor 2 for power are connected in series, the transistor 1 is turned ON-OFF, and the power of the load 4 is controlled by changing the time ratio of the ON-OFF. Signals turning the transistor 2 ON are provided to a gate of the transistor 2 for (tr+to+tf). Where tr and tf are rising time and falling time in case of the transition of the transistor 1. Thus, since the switching transient time of the field-effect transistor 2 is extremely short, the voltage for the switching transient time (tr, tf) of the transistor 1 is decreased, and power loss can be reduced.
