Abstract

Convertisseur à transistors pour l'alimentation en tension de lampes fluorescentes. Le transformateur 2 du convertisseur comporte des enroulements secondaires 14, 16 pour la tension alternative de chauffage, de travail et d'allumage, ainsi que des éléments de commutation statiques par l'intermédiaire desquels, après chaque mise en circuit de la tension continue d'alimentation (entrées 3, 4), la tension alternative de travail est débitée avec un certain retard vis-à-vis de la tension alternative de chauffage. L'invention est utilisée pour l'alimentation en tension des lampes fluorescentes en vue d'en prolonger la durée de vie sans solliciter continuellement une batterie.
