Abstract
L'invention concerne un appareil d'éclairage pour lampe à décharge, comprenant une alimentation électrique en courant continu (1), un circuit inverseur composé d'éléments de commutation (2, 3) pour convertir le courant continu de l'alimentation électrique (1) en courant haute fréquence, lequel éclaire la lampe à décharge (5). Une bobine d'arrêt (4) limite le courant de la lampe à décharge (5), à laquelle est couplé en série un condensateur de couplage (7). Un transformateur de courant (21) pourvu d'un enroulement secondaire est connecté, côté entrée, au joint de la lampe à décharge (5) et au condensateur de couplage (7) et, côté sortie, à la face haute tension et basse tension de l'alimentation électrique en courant continu (1), au moyen de diodes (20, 19) respectives. Un circuit de protection (9) stoppant l'oscillation du circuit inverseur est basé sur la tension induite dans l'enroulement secondaire du transformateur de courant (21).
