Abstract

L'invention a pour objet une alimentation régulée délivrant une tension continue pouvant prendre différentes valeurs. Elle comporte un transformateur bidirectionnel dont un premier enroulement en série avec un premier transistor commandé en saturation est alimenté par une source de tension continue et est couplé à un deuxième enroulement relié à un circuit de redressement et de filtrage pour permettre d'obtenir la tension continue de sortie pouvant être commutée d'une première valeur à une deuxième valeur supérieure et permettre de la maintenir constante, et dont un troisième enroulement est couplé au deuxième enroulement sur lequel est également monté un deuxième transistor commandé en saturation pour permettre une récupération d'énergie dans un condensateur monté en parallèle sur la source lors d'une brusque diminution de valeur de la tension de sortie. Application : alimentation THT pour unité cathodique polychrone.
