Abstract
L'invention concerne un circuit de commande d'un onduleur à thyristors en pont ou demi-pont Il comporte : un circuit de temporisation permettant de régler la puissance effectivement délivrée par l'onduleur avec des échelons ou pas égaux à des multiples entiers d'une fraction prédéterminée de la puissance maximale par la variation du rapport cyclique du fonctionnement de l'onduleur, de synchroniser les démarrages et les redémarrages de l'onduleur avec les passages par zéro du secteur et de visualiser à l'aide d'un voyant le fonctionnement normal ou défectueux (dû à une surcharge) de l'onduleur. L'invention est applicable aux onduleurs, notamment dans un appareil de chauffage par induction, tel que des plaques de cuisson
