グチョークコンバータ。A switching transistor is connected in series to the secondary winding of a transformer having a primary winding, a secondary winding, and a feedback winding to intermittent current in the secondary winding, and a switching transistor is provided on the secondary winding side. In a ringing choke converter that extracts an output voltage from a rectifying and smoothing circuit, the feedback winding includes a current limiting circuit constituted by a rectifying diode, a photocoupler light receiving element in series with the rectifying diode, or a Darlington connection of the light receiving element and a transistor. A control circuit is provided on the secondary winding side to detect the output voltage, and the control circuit drives the light emitting element of the photocoupler to A ringing choke converter, characterized in that the base current of a switching transistor is controlled to stabilize the output voltage.
