Abstract

La présente invention concerne un dispositif permettant la stabilité de fonctionnement des lampes à décharge. Ce dispositif est destiné à l'alimentation d'une lampe à décharge 1 munie de son appareillage comprenant une self 2 et une capacité 3, et il comprend en outre une self induction 4 shunta le par un interrupteur 5, ainsi qu'un variateur 6, le tout étant branché entre le neutre N et une phase P de l'installation. Application à la réduction de puissance des lampes à décharge.
