Transistor inverter device.

摘要

A transistor inverter device includes a capacitor (12) combined with an input winding (161) of a transformer (16) to form a resonance circuit and supplying to a transistor (14) a collector current having a large peak value. An inductor (24) is connected between the base and the emitter of the transistor (14). The inductor (24) generates reverse electromotive force according to a collector current flowing immediately before the transistor (14) is turned off and applied this reverse electromotive force between the base and the emitter of the transistor (14) as reverse bias. The switching operation of the transistor (14) from on-condition to off-condition is accelerated by this reverse bias of the inductor (24).
