Summary: | A heating device for tracking resonance frequency comprises: a parallel resonance circuit including a heating coil for heating a cooking appliance, an inductor including the heating coil, and a resonance capacitor resonating with the inductor; an inverter unit for supplying power to the parallel resonance circuit; a first current sensor for detecting an output current supplied from the inverter unit to the parallel resonance circuit; and a processor for controlling the driving frequency of the inverter unit so that the peak value of the output current detected by the first current sensor becomes smaller than a predetermined first threshold value.
L'invention concerne un dispositif de chauffage pour suivre une fréquence de résonance comprenant : un circuit de résonance parallèle comprenant une bobine de chauffage pour chauffer un appareil de cuisson, un inducteur comprenant la bobine de chauffage, et un condensateur de résonance résonant avec l'inducteur ; une unité d'onduleur pour fournir de l'énergie au circuit de résonance parallèle ; un premier capteur de courant pour détecter un courant de sortie fourni par l'unité d'onduleur au circuit de résonance parallèle ; et un processeur pour commander la fréquence d'entraînement de l'unité d'onduleur de telle sorte que la valeur de pic du courant de sortie détecté par le premier capteur de courant devient inférieure à une première valeur de seuil prédéterminée.
