Abstract

L'invention concerne un circuit régulé comprenant un circuit déflecteur avec une tension à la fréquence de déviation développée à sa première borne, une source d'énergie, un premier moyen de commutation réglable, un moyen de détection d'énergie produisant un signal d'erreur, un moyen de commande coup au premier moyen de commutation et sensible au signal d'erreur pour contrôler la durée de conduction du premier moyen de commutation, et un second moyen de commutation en parallèle au premier qui est décommuté par la tension à la fréquence de déviation, le second moyen de commutation étant conducteur de courant quand le premier est décommuté. Selon l'invention, le premier moyen de commutation réglable 33 est polarisé pour conduire un courant opératif direct pour transférer une quantité contrôlée d'énergie au circuit déflecteur 24 de la source B+, et le second moyen de commutation 34 est conducteur d'un courant de retour vers la source d'énergie. L'invention s'applique notamment aux téléviseurs.
