Abstract

L'invention concerne un régulateur de commutation adapté à un fonctionnement synchronisé avec un appareil de charge pouvant être excité par une source de tension continue non régulée. Selon l'invention, il comporte un moyen réglable de commutation 16 avec une électrode de commande (base) et un trajet conducteur de courant principal (émetteur-collecteur) définissant des première et seconde bornes 12 et A, la première borne 12 étant reliée à une borne de la source; un filtre comportant une self 18 relié à la seconde borne A et à une partie de l'appareil de charge 52 pour exciter cette partie d'une tension sensiblement constante; et un moyen de commande de tension relié à l'électrode de commande et à la seconde borne A pour contrôler le temps de commutation pour maintenir la tension moyenne à la seconde borne A à une valeur constante L'invention s'applique notamment aux téléviseurs.
