Abstract

PURPOSE: To shorten turn-OFF time of a transistor for conversion by a method wherein charged electric charge of a capacitor is fed back in the opposite direction to a base of the transistor for conversion through a switching element.
CONSTITUTION: A series circuit of the switching element SCR and the capacitor C1 is connected in parallel with a base driving circuit element of the transistor Q for conversion containing the feed back winding NB of a transformer T for conversion and an emitter resistor R2. A control winding NC to generate a voltage being proportional to the secondary winding NS of the transformer T for conversion is connected to both the ends of the capacitor C1 through a diode D1 for rectification. The switching element SCR is made to conduct to make charged electric charge of the capacitor C1 to be fed back to the base of the transistor Q for conversion in the opposite direction, and the transistor Q for conversion is made to OFF forcibly.
