Abstract

L'invention concerne un changeur de prises en charge pour réguler la tension avec des unités de commutation à semi-conducteurs au niveau d'un transformateur de réglage comportant un enroulement de réglage. Il est prévu deux branches de charge parallèles dans lesquelles sont disposées plusieurs unités de commutation à semi-conducteurs respectivement couplées en série. Des parties de l'enroulement de réglage ainsi que des ponts sont couplés en parallèle de manière alternée entre les deux branches de charge, de sorte que les parties de l'enroulement de réglage puissent être mises sous tension ou montées en opposition.
