Abstract

L'invention concerne un circuit auto-oscillateur réglable du type ballast de haut rendement, notamment prévu pour la commande de lampes fluorescentes. Selon l'invention, le circuit ballast comprend un redresseur double alternance relié à une source de courant alternatif et à un oscillateur réglable qui est, à son tour, connecté à un circuit de commande de la charge et à un circuit de commande de l'oscillateur. Un second redressseur, relié au circuit de charge, est disposé dans une boucle de contre-réaction, et permet d'assurer la charge d'un condensateur de façon à appliquer une tension pratiquement constante à l'oscillateur, ce dernier étant commandé par le courant appliqué au circuit de charge, la boucle de contre-réaction comprend en outre des moyens de protection contre les courants transitoires. Application : commande des lampes fluorescentes.
