<p>A control device for a resonant converter is described. Said converter comprises a switching circuit (Q1-Q2) adapted to drive a resonant load (30) and the resonant load comprising at least one capacitor (Cr); the converter is adapted to convert a source signal (Vin) into an output signal (Vout) and the switching circuit comprising at least a half bridge of first (Q1) and second (Q2) switches, the central point (HB) of said half bridge being connected to the resonant load (30). The control device comprises means (201, 202) adapted to generate at least a control signal (HSGD, LSGD) of the switching circuit by comparing a signal (Vcr) representative of the energy (Ein) transferred from the source signal (Vin) to the resonant load (30) with at least another signal (Vcm1, Vcm2, Vthp, Vthn).</p> |
