ク・コンバータ。[Claims for Utility Model Registration] A converter transformer having an input winding, an output winding, and a base drive winding, a collector-emitter path being connected in series to the input winding, and the emitter being one end of the base drive winding. and a switching transistor connected to the series connection, and by applying an input DC voltage to both ends of the series connection, a voltage generated in the input winding is induced in the output winding based on the operation of the switching transistor. In a ringing current converter that obtains an output DC voltage, a ringing transistor is connected between the other end of the base drive winding and the base of the switching transistor, and the voltage generated in the base drive winding is accumulated at both ends of the switching transistor. a diode circuit, which is a series circuit consisting of two or more diodes and is connected in parallel to the capacitor, and delays the ON operation of the switching transistor by limiting the voltage accumulated across the capacitor. A ringing chiyoke converter characterized by comprising the following.
