Abstract

CIRCUIT D'ALIMENTATION D'UNE LAMPE A DECHARGE. IL COMPORTE UNE SOURCE D'ENERGIE ELECTRIQUE 11 FOURNISSANT A SA SORTIE UNE TENSION CONTINUE ET ETANT CAPABLE DE REPRENDRE DE L'ENERGIE ELECTRIQUE ET UN CIRCUIT DE TRANSFERT D'ENERGIE INSERE ENTRE LA SOURCE D'ENERGIE ELECTRIQUE ET UN PREMIER CONDENSATEUR 19 RELIE A LA LAMPE POUR EMMAGASINER L'ENERGIE NECESSAIRE POUR CHAQUE DECHARGE A TRAVERS LA LAMPE, LE CIRCUIT DE TRANSFERT D'ENERGIE COMPORTANT L'ENROULEMENT PRIMAIRE 16 D'UN AUTOTRANSFORMATEUR ET PERMETTANT LE PASSAGE DU COURANT VERS LE PREMIER CONDENSATEUR JUSQU'A CE QUE CELUI-CI ATTEIGNE UNE VALEUR DE TENSION PRE-DETERMINEE, ET UN DEUXIEME CONDENSATEUR 25 QUI SERT A EMMAGASINER UN SURPLUS D'ENERGIE NON UTILISEE EMMAGASINEE DANS L'AUTOTRANSFORMATEUR LORS DE LA CHARGE DU PREMIER CONDENSATEUR.
