Abstract

L'invention porte sur un dispositif de chauffage à induction, dans lequel dispositif, au commencement d'une alimentation en énergie respective pour une pluralité d'enroulements chauffants, une commande de démarrage souple est effectuée, de telle sorte que la puissance fournie aux enroulements chauffants est progressivement accrue à partir d'une valeur minimale prédéfinie et devient une valeur de puissance stable. Après que la puissance fournie aux enroulements chauffants a atteint la valeur de puissance stable, un circuit onduleur est commandé de façon à maintenir une alimentation de la valeur de puissance stable, jusqu'au point d'achèvement de l'alimentation des enroulements chauffants. La valeur de puissance stable est établie de façon à être supérieure à la valeur de puissance moyenne fournie aux enroulements chauffants.
