Abstract

L'invention concerne un régulateur comprenant un circuit convertisseur résonant qui limite la tension appliquée à une lampe lorsqu'elle ne s'allume pas. Dans une forme d'exécution, le régulateur comprend un premier et un second élément de commutation dont les états de conduction sont commandés respectivement par un premier et un second circuit de commande. Le second circuit de commande comprend un troisième élément de commutation qui commande l'état de conduction du second élément de commutation. Un circuit de fin de vie comprend un premier circuit à seuil couplé au troisième élément de commutation de manière à pouvoir neutraliser le convertisseur lorsque la tension appliquée à la lampe dépasse un premier seuil prédéterminé. Dans une forme d'exécution différente, le second circuit de commande comprend un quatrième élément de commutation permettant de commander le facteur de charge du troisième élément de commutation et le circuit de fin de vie comprend un second circuit à seuil. Lorsque la tension dans la lampe dépasse un second seuil prédéterminé, le quatrième élément de commutation réduit le facteur de charge du troisième élément de commutation.
