Abstract

La présente invention concerne un régulateur de commutation pour un téléviseur, comprenant un commutateur réglable, une inductance et un générateur de déviation horizontale formant un premier trajet en série relié à une source de tension continue non régulée. Selon l'invention, on prévoit un moyen d'accouplement 20, une diode 24, un condensateur 18, et un moyen de contrôle 36. L'invention s'applique notamment aux téléviseurs en couleurs.
