A ringing choke-type DC/DC converter comprising a transformer having a primary winding, a secondary winding, and a feedback winding, an input DC power source connected through a transistor to the primary winding of the transformer, a DC power output connected through a diode to the secondary winding of the transformer, a base circuit having a first capacitor and connected between the base of the transistor and the feedback winding of the transformer, a branch circuit branching from the base circuit and having a Zener diode connected in series with a second capacitor, and an impedance provided in series between the transistor and the branch circuit for preventing the transistor from intermittently operating, thereby stabilizing the DC power output.
