Abstract

L'invention concerne un circuit déflecteur magnétiquement régulé. Selon l'invention, il comprend un moyen magnétique de commutation 42, 43 ayant un premier enroulement de charge appliquant une source UB d'énergie non régulée et une source 38 d'énergie à la fréquence de déviation au circuit déflecteur 50 quand il est mis en court-circuit par saturation magnétique de son noyau; et un circuit de réglage 25 relié au moyen magnétique de commutation et sensible au niveau d'énergie du circuit déflecteur 50 pour faire varier l'intervalle de court-circuit L'invention s'applique notamment aux téléviseurs.
