Abstract

L'invention concerne un système de changement de prise de transformateur en charge dans lequel le secondaire ou le primaire d'un transformateur comporte au moins une première et une deuxième prises (p1, p2). Un circuit de connexion principal (tra-I2) permet de connecter de façon permanente la première prise (p1) ou la deuxième prise (p2) à une borne de sortie (b2) du secondaire ou du primaire du transformateur. Des circuits de connexion secondaire (I1, I3) permettent de connecter chacun une prise (p1, p2) temporairement et directement à ladite borne de sortie (b2) du secondaire ou du primaire du transformateur. Chacun desdits circuits de connexion (I1, tra-I2, I3) comporte un ou plusieurs transistors bipolaires à grilles isolées et la commande du système peut se faire sans détection du passage par zéro de la valeur du courant dans l'enroulement secondaire.
