特徴とするリンギングチヨークコンバータ。 A transformer having a main winding and a feedback winding on a primary side and an output winding on a secondary side, and a collector current is supplied from a DC power source through the main winding in an on state, and the feedback winding a switching transistor to which a base current is positively fed back through the switching transistor, and a ringing device configured to release energy stored in the main winding when the transistor is on through the output winding when the transistor is off. In the choke converter, a capacitor is charged via a diode by an electromotive force induced in the feedback winding when the transistor is off, and the feedback winding is charged when the terminal voltage of this capacitor exceeds a predetermined value. A ringing chain converter comprising: a nonlinear circuit element that bypasses a base current that is positively fed back to the transistor from a line; and a variable resistor that is connected in series with the diode and changes the terminal voltage of the capacitor. .
