Abstract

L'INVENTION CONCERNE LA STABILISATION DES DECHARGES DANS LES LASERS A GAZ. ELLE SE RAPPORTE A UN CIRCUIT QUI COMPORTE UN THYRISTOR7 MONTE EN SERIE AVEC UN CONDENSATEUR8, AUX BORNES DE CHAQUE CIRCUIT FORME PAR UN SEGMENT3 COMPRENANT DES ANODES INDIVIDUELLES 4, ET UNE PARTIE DE LA CATHODE2. UN COMPOSANT INDUCTIF PRINCIPAL6 EST MONTE EN SERIE AVEC CHAQUE SEGMENT ANODIQUE, ET A UN SECONDAIRE10 QUI COMMANDE LA CONDUCTION DU THYRISTOR7 PAR SA GACHETTE. APPLICATION AUX LASERS DE PUISSANCE UTILISES POUR LE SOUDAGE ET LE COUPAGE.
