Abstract

Transformateur réglable statique pour la production de tensions et/ou de courants variables, à partir d'une tension alternative constante appliquée au primaire. Des premiers interrupteurs électroniques Ai sont disposés entre deux enroulements partiels de secondaire Wi . On applique des impulsions de comptage à un compteur binaire 2. Chaque sortie du compteur binaire est réunie à l'électrode de commande de l'un des interrupteurs Ai . Des seconds interrupteurs électroniques B i sont montés en dérivations sur le groupement série d'un enroulement partiel Wi et d'un premier interrupteur Ai , et sont commandés par les sorties du compteur binaire 2 de sorte que lorsque un premier interrupteur A est ouvert, le deuxième B i , correspondant, se ferme et vice-versa. Applications : aux transformateurs statiques.Static adjustable transformer for the production of variable voltages and / or currents, from a constant alternating voltage applied to the primary. First electronic switches Ai are arranged between two partial windings of secondary Wi. Counting pulses are applied to a binary counter 2. Each output of the binary counter is joined to the control electrode of one of the switches Ai. Second electronic switches B i are mounted in branches on the series grouping of a partial winding Wi and a first switch Ai, and are controlled by the outputs of binary counter 2 so that when a first switch A is open, the second B i, corresponding, closes and vice versa. Applications: to static transformers.
