Abstract

Un procédé de commande en puissance d'au moins un inducteur (L) recouvert d'un récipient et alimenté en courant alternatif par un dispositif d'alimentation à onduleur (20) commandé par un signal de commande périodique comprend les étapes suivantes : - choix d'une fréquence pour le signal de commande périodique parmi un ensemble de N valeurs de fréquences prédéfinies, N étant égal ou supérieur à deux ; et - ajustement d'un rapport cyclique du signal de commande périodique à la fréquence choisie pour obtenir une puissance induite dans le récipient. Utilisation dans les tables de cuisson à induction, notamment sans foyer de cuisson prédéfini dans le plan de cuisson. Figure pour l’abrégé : Fig. 2A method for controlling the power of at least one inductor (L) covered with a container and supplied with alternating current by an inverter supply device (20) controlled by a periodic control signal comprises the following steps: - choosing a frequency for the periodic control signal from among a set of N predefined frequency values, N being equal to or greater than two; and - adjustment of a duty cycle of the periodic control signal at the chosen frequency to obtain a power induced in the container. Use in induction hobs, in particular without a predefined cooking zone in the hob. Figure for abstract: Fig. 2
