Claim:
1. A resonant converter, comprising: a primary switching circuit having at least a primary winding and a primary full-bridge switching stage, which is configured for driving said primary winding, and an inductor in series with the primary winding, the primary full-bridge switching stage including high-side and low-side switches; a secondary resonant circuit having a secondary winding magnetically coupled to the primary winding, a resonance capacitor electrically connected in parallel to the secondary winding, a first secondary inductor and a second secondary inductor, each secondary inductor connected between an output terminal of the converter and a respective terminal of the resonance capacitor; a secondary rectification stage electrically connected in parallel to the resonance capacitor, the secondary rectification stage having a first switch and a second switch each connected between a respective terminal of the resonance capacitor and ground; and a driving module configured to receive at an input an enabling signal and a voltage measured across one of the switches of the secondary side, said module being configured for generating a control signal for controlling the switches of the secondary side, the driving module configured to cyclically,
