Abstract

L'invention concerne un circuit de commande pour lampe à décharge, comprenant un condensateur de lissage (C2) et un commutateur (SW3) montés en série entre une extrémité du côté lampe à décharge (LMP) d'un réacteur (L1) et une extrémité d'un convertisseur (COMV). Le commutateur (SW3), lorsqu'il est ouvert, permet d'enlever le condensateur de lissage (C2) du circuit, lors de l'étape initiale d'allumage de la lampe à décharge (LMP), pour augmenter la tension V2 au niveau du point de connexion entre le réacteur (L1) et le condensateur de lissage (C2) et ainsi augmenter la vitesse de réponse aux variations de charge lorsque le courant traversant la lampe (LMP) est interrompu. Le commutateur (SW3) est activé après que le courant traversant la lampe (LMP) a été stabilisé, pour insérer le condensateur de lissage (C2) dans le circuit.
