Abstract
A DC/DC converter includes a first capacitor and a second capacitor coupled to a first node, a first switch and a second switch coupled between the first node and a second node, a third switch and a fourth switch coupled between the first node and a third node, a first passive network coupled between a fourth node and a fifth node, the first passive network connecting the fourth node and the fifth node in series to a primary winding of a transformer, and a secondary side circuit coupled to a secondary winding of the transformer; a control method of the DC/DC converter includes: adjusting a phase shift angle between control signals of the first switch and the fourth switch to reduce a voltage difference between the first capacitor and the second capacitor.
