Abstract

L'invention concerne un régulateur de commutation adapté à un fonctionnement synchronisé avec un appareil de charge pouvant être excité par une source de tension continue non régulée. Selon l'invention, il comporte un moyen réglable de commutation 16 avec une électrode de commande (base) et un trajet conducteur de courant principal (émetteur-collecteur) définissant des première et seconde bornes 12 et A, la première borne 12 étant reliée à une borne de la source; un filtre comportant une self 18 relié à la seconde borne A et à une partie de l'appareil de charge 52 pour exciter cette partie d'une tension sensiblement constante; et un moyen de commande de tension relié à l'électrode de commande et à la seconde borne A pour contrôler le temps de commutation pour maintenir la tension moyenne à la seconde borne A à une valeur constante L'invention s'applique notamment aux téléviseurs.A switching regulator suitable for synchronized operation with a load device which can be energized by an unregulated DC voltage source is disclosed. According to the invention, it comprises an adjustable switching means 16 with a control electrode (base) and a main current conducting path (emitter-collector) defining first and second terminals 12 and A, the first terminal 12 being connected to a source terminal; a filter comprising an inductor 18 connected to the second terminal A and to a part of the charging device 52 to excite this part with a substantially constant voltage; and a voltage control means connected to the control electrode and to the second terminal A for controlling the switching time to maintain the average voltage at the second terminal A at a constant value. The invention applies in particular to television sets.
