<p>PROBLEM TO BE SOLVED: To provide a DC-DC converter capable of maintaining power supply efficiency while properly controlling an output voltage.SOLUTION: The DC-DC converter includes: a smoothing capacitor; a switching circuit; and a capacitor circuit on the primary and secondary sides of a high-frequency transformer. When voltage detection means detects a midpoint voltage of the capacitor circuit, timing signal output means generates a timing signal synchronous with a period at which a winding voltage of the high-frequency transformer changes on the basis of a change in the midpoint voltage according to switching operations of the switching circuit and outputs it to a driving circuit.</p> |
