Abstract: In a monophase resonant converter comprising a primary switching circuit with one or more primary windings and a primary full-bridge switching stage configured to drive the primary winding (s) as well as a secondary resonant circuit having a secondary winding magnetically coupled to the primary winding, a resonance capacitor (CR) electrically connected in parallel to the secondary winding, and first (L1) and second (L2) secondary inductors connected between an output terminal of the converter and respective terminals of the resonance capacitor (CR), a secondary rectification stage is electrically connected in parallel with the resonance capacitor (CR), with a first (R1) and a second (R2) switch connected to form a half-bridge with an intermediate tap connected to ground.
A command method for such a resonant converter is disclosed including a sequence of steps to be performed cyclically.
