The control device comprises an error amplifier having an inverting terminal (Vout) and a non-inverting terminal receiving a reference voltage. The device includes first and second resistances coupled in series with a conduction element positioned between the first resistance and the inverting terminal of the error amplifier and a fault detector suitable for detecting the electrical connection of the conduction element with the output terminal and suitable for detecting an output signal of the second resistance. The fault detector is suitable for supplying a malfunction signal upon detecting an electric disconnection of the conduction element from the output terminal or when the output signal of the second resistance tends to zero.

摘要： A control device controls a switching circuit of a resonant converter having an output direct current. The switching circuit includes at least a half-bridge of at least a first and a second transistor connected between an input voltage and a reference voltage. The half-bridge is adapted to generate a periodic square-wave voltage for driving the resonant circuit of said resonant circuit and the periodic square-wave voltage oscillates between a high voltage corresponding to the input voltage and a low voltage corresponding to the reference voltage. The control device comprises a generator adapted to generate a periodic square-wave signal for driving the half-bridge. The control device comprises a detector adapted to detect the phase-shift between the periodic square-wave signal generated by the generating means and the current flowing through the resonant circuit, and adapted to control the turning off of the half-bridge when the phase-shift exceeds a first phase-shift value.
