Abstract

Une table de cuisson à induction alimentée par une tension alternative comporte au moins un système d'alimentation produisant une tension redressée et filtrée (V2), chaque système d'alimentation alimente au moins un dispositif à onduleur. Le procédé de commande comprend une étape de modification (10) de la commande dudit au moins un dispositif à onduleur lorsque la valeur instantanée de ladite tension redressée et filtrée (V2) d'alimentation dudit au moins un dispositif à onduleur est comprise entre le minima périodique et 20% de plus que ledit minima périodique ; ladite modification de la commande dudit au moins un dispositif à onduleur désignant le démarrage, la modification de la fréquence ou du rapport cyclique, ou l'arrêt du ou des signaux de commande dudit au moins un dispositif à onduleur.

Figure imgaf001
An induction cooktop powered by an AC voltage has at least one supply system producing a rectified and filtered voltage (V2), each supply system supplies at least one inverter device. The control method comprises a step of modifying (10) the control of said at least one inverter device when the instantaneous value of said rectified voltage and filtered (V2) supply of said at least one inverter device is between the minimum periodical and 20% more than said periodic minimum; said modification of the control of said at least one inverter device designating the start, the modification of the frequency or the duty cycle, or the stopping of the control signal (s) of said at least one inverter device.
