ようにしたことを特徴とするチョッパ型電源回路。The primary winding of an oscillating transformer and the collector emitter of a switching transistor are connected in series between the input end of a DC voltage and the output end connected to a smoothing capacitor, and the feedback winding of the transformer is connected to the switching transistor. The other end of the secondary winding of the transformer, which is connected between the base and emitter of the transistor and has a flywheel diode connected to one end, is connected to the output end, and in response to fluctuations in the DC output voltage obtained at the output end. In a power supply circuit formed by connecting the collector and emitter of a positive feedback current shunting transistor controlled by the switching transistor to the base and emitter of the switching transistor, the A pulse voltage generated in the feedback winding is applied as a reverse bias to the base of the control transistor through a capacitor, so that the control transistor is kept in an off state for a short period of time after the polarity reversal. Chopper type power supply circuit.
