Abstract

L'invention concerne une double alimentation résonnante en parallèle (20') pour lampe à décharge (22, 22') remplie de gaz. L'élément de commande (32') remplit des fonctions de blocage en cas de tension d'entrée insuffisante, de tension primaire excessive, et de déséquilibre de la tension de sortie principale qui permettent de couper l'alimentation lorsque des conditions de fonctionnement anormales sont détectées.
