Abstract
La présente invention concerne un dispositif de régulation pour un régulateur de courant alternatif constitué par des éléments redresseurs contrôlés et branché sur un transformateur. Un transformateur de courant 5, 6 est, dans chaque phase, affecté aux enroulements du transformateur 1a, 1b, et tous les transformateurs de courant branchés sur la même phase sont réunis en un circuit à alimentation différentielle, un dispositif de mesure 8 à 18 qui détermine pour chaque demi-alternance la valeur de crête de la grandeur différentielle formée, étant branché sur ledit circuit, dispositif de mesure dont le signal de sortie est introduit, en fonction de la polarité de la grandeur différentielle, dans le circuit de commande de l'une ou l'autre des branches du régulateur de courant alternatif. Le dispositif de régulation selon la présente invention est notamment utilisé pour les compensateurs de puissance réactive.
