Abstract
A resonant converter, including: a primary side circuit including at least one set of primary side switches, where the primary side circuit is configured to receive an input voltage; a resonant network coupled to the primary side circuit; a transformer having a primary side winding and a secondary side winding, where the primary side winding is coupled to the resonant network; a secondary side circuit including at least one set of secondary side switches, where the secondary side circuit is coupled to the secondary side winding of the transformer; and a control block that controls the secondary side switches according to the input voltage, the output voltage and the current detection signal, so that the secondary side winding of the transformer is short-circuited during a preset time interval before operating state of the primary side switches changes.
