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.- Direct current generator protected against transient or permanent overvoltages, whether or not it is supplied by its power supply. - The direct current generator protected against transient or permanent overvoltages comprises a shunt module (4) configured to be traversed by the electric current supplied by a power supply, a differential amplifier module (5) configured to determine a measurement voltage from 'a first electric potential and a second electric potential at the terminals of the shunt module (4), a comparator module (6) configured to perform a comparison between the measurement voltage and a predetermined reference voltage (Vref), a switch module progressive (7) configured to control the current of the current generator as a function of the voltage at the terminals of the shunt module (4) and a protection module (8) configured to block the overvoltage when it is of the same polarity as the current generator continuous and to quickly open the soft switch module (7) when the overvoltage is of reverse polarity to the current generator.
