Claims

[Claims for Utility Model Registration] An input voltage is applied to the primary coil of the transformer through the collector and emitter of a switching transistor connected in series, and at the same time, to the base of the switching transistor, The input voltage is applied through a starting resistor, and the voltage generated at the base drive coil of the transformer is applied to the transformer's secondary coil, which is connected in parallel with a diode connected in series. In a ringing converter, an output load is connected via a capacitor connected to a capacitor, and a predetermined voltage is applied to the output load. A ringing-choke converter characterized in that the generated voltage is applied to the output load as a start/stop signal for the output load via a hysteresis detection circuit.
