[Claims for Utility Model Registration] A DC power source is connected to a series circuit of a switching element consisting of a primary winding of a converter transformer and a transistor, and the base winding of the converter transformer is connected to the base of the transistor. At the same time, the DC power source is connected via a starting resistor, a rectifying and smoothing circuit for obtaining an output voltage is connected to the secondary winding of the converter transformer, and a voltage source at the level of the output voltage is connected to the base of the transistor. In a ringing chain converter type power supply device to which a circuit that draws current according to the output voltage is connected, a variable impedance element is connected in series with the starting resistor, and the impedance of the variable impedance element changes depending on the level of the output voltage. A ringing chain yoke converter type power supply device that is controlled by
