Abstract

Système électronique de coupure de courant doté d’une solution de coupure rapide. Un dispositif (10) électronique de coupure de courant comprenant au moins un transistor commandé (12), des moyens de mesure de courant (15), et une unité électronique de commande (16 couplée audit au moins un transistor commandé (12) et aux moyens de mesure de courant (15). L’unité électronique de commande (16) comprend :- un premier comparateur (160) configuré pour comparer au moins une mesure de courant à un seuil de courant, - un module (161) de détermination de la vitesse de variation du courant à partir d’au moins deux mesures de courant, - un second comparateur (162) configuré pour comparer au moins une vitesse de variation du courant à un seuil de vitesse de variation de courant, - un module de commande (163) configuré pour commander l’ouverture dudit au moins un transistor en fonction du résultat du premier comparateur (160) et du second comparateur (162). Figure pour l’abrégé : Fig. 4.Electronic power cut-off system with a quick cut-off solution. An electronic power cut-off device (10) comprising at least one controlled transistor (12), current measuring means (15), and an electronic control unit (16 coupled to said at least one controlled transistor (12) and to current measurement means (15). The electronic control unit (16) comprises: - a first comparator (160) configured to compare at least one current measurement with a current threshold, - a determination module (161) of the speed of variation of the current from at least two current measurements, - a second comparator (162) configured to compare at least one speed of variation of the current with a threshold of the speed of current variation, - a module of control (163) configured to control the opening of said at least one transistor according to the result of the first comparator (160) and of the second comparator (162) Figure for the abstract: Fig. 4.
