Abstract

Dispositif d'alimentation de tube fluorescent, comprenant un convertisseur 11 qui alimente un premier transformateur 201 pour chaque tube 101 . Le convertisseur alimente également un second transformateur 21 qui fournit une tension de préchauffage des cathodes du tube ou de chaque tube. Des moyens de commutation 17 retardent l'application de la haute tension d'une durée déterminée à partir de l'application de la tension de préchauffage. Applications courantes.
