Abstract

L'INVENTION CONCERNE UN DISPOSITIF DEFLECTEUR DE TELEVISION REGULE POUVANT ETRE EXCITE PAR UNE SOURCE DE TENSION CONTINUE NON REGULEE ET EN ETRE ISOLE. SELON L'INVENTION, IL COMPREND UN COMMUTATEUR REGULATEUR 26 AYANT UN TRAJET DE COURANT REGLE ET UNE ELECTRODE DE COMMANDE; UN TRANSFORMATEUR 24 AVEC UN ENROULEMENT PRIMAIRE 24A EN SERIE AVEC LE TRAJET DE COURANT PRINCIPAL ET AVEC LA SOURCE 10 ET AYANT UN ENROULEMENT SECONDAIRE 24D; UN ENROULEMENT DEFLECTEUR 50 RELIE A L'ENROULEMENT SECONDAIRE 24D, UN COMMUTATEUR D'ALLER 44 RELIE EN PARALLELE A L'ENROULEMENT DEFLECTEUR, ET UN MOYEN DE COMMANDE 68 RELIE A L'ELECTRODE DE COMMANDE ET A UN POINT DE DETECTION D'ENERGIE POUR CONTROLER LE TEMPS, PENDANT L'INTERVALLE D'ALLER, OU LE COMMUTATEUR REGULATEUR EST PASSANT AFIN DE MAINTENIR LA TENSION A CE POINT SENSIBLEMENT CONSTANTE. L'INVENTION S'APPLIQUE NOTAMMENT AUX TELEVISEURS.
