Abstract
- Générateur de courant continu protégé contre des surtensions transitoires ou permanentes, qu'il soit ou non alimenté par son alimentation. - Le générateur de courant continu protégé contre des surtensions transitoires ou permanentes comprend un module shunt (4) configuré pour être traversé par le courant électrique fourni par une alimentation, un module amplificateur différentiel (5) configuré pour déterminer une tension de mesure à partir d'un premier potentiel électrique et d'un deuxième potentiel électrique aux bornes du module shunt (4), un module comparateur (6) configuré pour effectuer une comparaison entre la tension de mesure et une tension de référence (Vref) prédéterminée, un module interrupteur progressif (7) configuré pour asservir le courant du générateur de courant en fonction de la tension aux bornes du module shunt (4) et un module de protection (8) configuré pour bloquer la surtension quand elle est de même polarité que le générateur de courant continu et pour ouvrir rapidement le module interrupteur progressif (7) lorsque la surtension est de polarité inverse au générateur de courant.
