Abstract

La présente invention concerne un régulateur de tension électrique permettant de réguler une tension de charge. Ce régulateur est capable d'exécuter relativement facilement une combinaison d'opérations d'élévation de la tension, de baisse de la tension et de passage à une phase neutre, de commuter les bornes ou polarités des primaires de transformateurs chargés montés en série sans court-circuit instantané de rupture ni modification du rapport des nombres de spires pour faire revenir à l'état non excité les transformateurs montés en série. Ce régulateur est également capable de réguler la tension de charge grâce à un transformateur auxiliaire. Selon une première réalisation, le régulateur de tension électrique est constitué de transformateurs montés en série, d'un commutateur comprenant uniquement un dispositif à semi-conducteur à fonction de blocage automatique ne comportant pas de circuit de puissance pour limiter un éventuel phénomène de surtension lors de la commutation d'un circuit, d'un simple limiteur de surtension mis en oeuvre au moment de la permutation de circuit, et d'un circuit de commande permettant d'exécuter l'opération de commutation à grande vitesse (Voir Figure 1). Selon une seconde réalisation, le régulateur de tension électrique est constitué d'un autotransformateur, d'un commutateur comprenant un dispositif à semi-conducteur à fonction de blocage automatique et assurant la commutation des bornes ou des connexions série des enroulements de façon à fair varier le nombre effectif de tours d'une partie commune d'enroulement de l'autotransformateur, et d'un simple limiteur de surtension mis en oeuvre au moment de la commutation des bornes, et d'un circuit de commande permettant d'exécuter l'opération de commutation à grande vitesse (Voir Figure 2).
