DC/DC CONVERTER

WIPO Patent Application WO/2023/157916

A1

Provided is a DC/DC converter 1A comprising a transformer 10, a primary-side switching circuit 11, a primary-side resonance circuit 12, a secondary-side rectifier circuit 13, and a control unit 14A that controls the primary-side switching circuit 11, characterized in that when the output of the secondary-side rectifier circuit 13 is reduced to or below a prescribed value from a first state in which three phase differences between each of first, second, and third legs of the primary-side switching circuit 11 are all a first phase difference, the control unit 14A performs a first phase shift control that simultaneously increases two of the three phase differences and decreases the one remaining phase difference or performs a second phase shift control that simultaneously decreases two of the three phase differences and increases the one remaining phase difference.
