Abstract

L'INVENTION CONCERNE UNE SOURCE D'ALIMENTATION EN COURANT POUR UN SYSTEME DE TELEVISION AVEC UNE SOURCE DE TENSION D'ENTREE, UN MOYEN DEVELOPPANT UN COURANT D'EXCITATION, UN NOYAU MAGNETISABLE AYANT UNE SECTION SATURABLE, UN ENROULEMENT SUR LE NOYAU, UN MOYEN Y PRODUISANT UN FLUX MAGNETIQUE POUR DEVELOPPER UNE TENSION DE SORTIE DE POLARITE ALTERNANTE, UNE CAPACITE DEVELOPPANT UN COURANT EN CIRCULATION PRODUISANT UNE FORCE DE MAGNETISATION DANS LA SECTION SATURABLE, UNE BORNE FINALE ET UN MOYEN REPONDANT A LA TENSION DE SORTIE POUR DEVELOPPER UNE TENSION FINALE. SELON L'INVENTION, UN AIMANT PERMANENT 22 POLARISE LE NOYAU 21 AFIN DE PRODUIRE UNE SECONDE FORCE DE MAGNETISATION DANS SA SECTION SATURABLE ET, LA RESULTANTE DES FORCES DEVELOPPANT UN FLUX MAGNETIQUE SATURANT CETTE SECTION. L'INVENTION S'APPLIQUE NOTAMMENT A LA TELEVISION.
