Abstract
A power conversion circuit includes a first branch having a first switch and a second switch electrically connected to each other in series between a first node and a second node. An inductive element has a first terminal connected to a mid-point of the first and second switches. A capacitor has a first electrode coupled to the first node. A third node is configured to receive a first voltage, and the first voltage is referenced to the second node. A third switch is configured to electrically connect the third node to a second terminal of the inductive element.
