Abstract
The present disclosure discloses a resonant converter, and a controlling method thereof. The resonant converter includes a transformer including a primary winding and a secondary winding, a primary circuit electrically connected to the primary winding and receiving an input voltage, and a secondary circuit electrically connected to the secondary winding and outputting an output voltage. The secondary circuit includes a first secondary half-bridge including a first controllable switch and a second secondary half-bridge including a second controllable switch connected in parallel. The first and second controllable switches are arranged diagonally. The method includes: controlling a duty ratio of one of the first controllable switch and the second controllable switch in a first switching period to form a first short-circuited loop during a first interval during; and controlling a duty ratio of the other one in a second switching period to form a second short-circuited loop during a second interval.
