Title (EN) DEVICE FOR CHARGING ELECTRICAL ENERGY STORAGE MEANS PROVIDED WITH MEANS FOR CONTROLLING SAID CHARGING
(FR) DISPOSITIF DE CHARGE DE MOYENS D'ACCUMULATION D'ENERGIE ELECTRIQUE, MUNI DE MOYENS PERMETTANT DE MAITRISER CETTE CHARGE
Abstract:
(EN) The device comprises means (S) for continuously supplying electricity to storage means (C), switching means (K) linking the supply means and the storage means which can be charged when said switching means is closed, control means (cm) for comparing the voltage at the connectors of the storage means with a predetermined voltage threshold, and for controlling the opening of the switching means once said voltage reaches the threshold, a temporary magnetic energy inductive storage means, and means (T) for diverting excess electrical energy, essentially of magnetic origin, which may arise in the device while the storage means are being charged, towards means (S; 26) which can absorb said excess energy. The device can be used to supply a metal vapour laser.
(FR) Il comprend des moyens (S) d'alimentation électrique continue des moyens d'accumulation (C), des moyens de commutation (K) qui relient les moyens d'alimentation aux moyens d'accumulation et dont la fermeture permet la charge de ces derniers, des moyens de commande (cm) pour comparer à un seuil de tension déterminé la tension aux bornes des moyens d'accumulation et pour commander l'ouverture des moyens de commutation lorsque le seuil est atteint par cette tension, un moyen inductif d'accumulation temporaire d'énergie magnétique et des moyens (T) pour dérouter une énergie électrique excédentaire, essentiellement d'origine magnétique, susceptible d'apparaître dans le dispositif, au cours de la charge des moyens d'accumulation, vers des moyens (S; 26) capables d'absorber cette énergie excédentaire. Application à l'alimentation d'un laser à vapeur métallique.
