Abstract
L'invention concerne un circuit auto-oscillateur de type ballast à commande directe, notamment prévu pour la commande de lampes fluorescentes. Selon l'invention, le circuit ballast comprend un redresseur 7, un oscillateur haute fréquence 9, un circuit de commande 13 de l'oscillateur disposé en série avec la charge 11, une boucle de réaction 15 permettant d'appliquer une tension au condensateur d'une branche 17, délivrant une tension pratiquement constante à l'oscillateur 9 et, commandant le circuit de démarrage 19 constitué par un oscillateur à relaxation. Application : lampes fluorescentes.
