Abstract

a. Montage pour dériver le courant de coupure d'un appareil utilisateur inductif. b. Montage caractérisé en ce qu'un commutateur à semi-conducteur à libre passage est prévu, dont l'électrode de commande est reliée à un des pôles de la source de tension d'alimentation et dont la voie de commutation shunte les deux bornes du transistor de commutation. c. L'invention s'applique notamment à la commande des enroulements de relais.
