Abstract

A resonant converter includes primary and secondary circuits, a transformer, a resonant network and a control circuit. The control circuit is coupled to the primary circuit and the secondary circuit, and configured to control primary switches of the primary circuit operating with a switching frequency. At least one of primary switches is configured to be turned on from a first switching moment until a second switching moment. The control circuit is configured to control secondary switches of the secondary circuit, such that at least one of secondary switches is turned on during a first time interval to increase a current of the resonant network in a first flowing direction and an output current in a second flowing direction or equal to zero.
