Abstract

L'invention concerne un dispositif à transformateur pour un circuit de déviation verticale à commutation synchrone. Un circuit de déviation horizontale 7, 11 commande un générateur de tension par un premier transformateur 8 et commande également un circuit de déviation verticale à commutation synchrone. De façon à réduire les variations de l'énergie entre le circuit de deviation horizontale et le circuit de déviation verticale du fait des variations de la charge 9 associée au générateur, le circuit de déviation horizontale est couplé au circuit de déviation verticale par des seconds transformateurs 26, 27 séparés dudit premier transformateur 8. L'invention s'applique notamment aux récepteurs de télévision couleurs.
