摘要： This DC-DC converter circuit includes a switching circuit which switches a DC power supply with a primary side switching element, a transformer to a primary side winding whereof the output of the switching circuit is applied and which outputs a voltage which has been changed by a predetermined voltage change ratio to a secondary side winding, and secondary diodes for current adjustment connected to the secondary side winding of the transformer. Moreover, it includes a regeneration snubber circuit connected in parallel with the secondary diode circuit and including a series circuit of a discharge blocking diode and a snubber capacitor and a switching element for regeneration connected in parallel with the discharge blocking diode, a filter circuit connected between rectification outputs of the secondary diode circuit, and a control unit which turns the switching element for regeneration ON a predetermined time period after the timing of turning the primary side switching element OFF. The predetermined time period is set to approximately the time period during which the charge, accumulated in the snubber capacitor due to reverse recovery time when one of the secondary diodes has been turned OFF, discharges.
