Patent ID: 11387742

Abstract:
A full-bridge resonant conversion circuit comprises a full-bridge rectification unit, a resonant unit, a first transformer, a second transformer and a synchronous rectification unit, wherein the full-bridge rectification unit comprises a first connection end and a second connection end, the resonant unit comprises a first resonant inductor, a resonant capacitor and a second resonant inductor, the resonant capacitor is connected in series with the first resonant inductor or the second resonant inductor. The first transformer comprises a first primary winding connected in series with the first resonant inductor, and a first secondary winding. Also, the second transformer comprises a second primary winding connected in series with the first primary winding and connected with the second resonant inductor, and a second secondary winding connected in parallel with the first secondary winding, and the synchronous rectification unit is connected with the first secondary winding and the second secondary winding.
