Abstract
(EN)
A protection circuit(100) for ground short circuit protection, the circuit(100) comprising: a high conduction circuit(110) for controlling the supply of electric power for a functional circuit(1000), wherein the functional circuit(1000) has a boost function; and a charging subcircuit(120) for controlling, based on an input voltage of an input power source of the protection circuit(100) and an output voltage from the functional circuit(1000), the high conduction circuit(110) to be turned on or turned off; and an energy storage circuit(130) for storing electric power from the input power source so as to provide electric power for the functional circuit(1000).
(FR)
L’invention concerne un circuit de protection (100) pour la protection contre les courts-circuits à la masse, le circuit (100) comprenant : un circuit à haute conduction (110) destiné à contrôler l’alimentation en puissance électrique pour circuit fonctionnel (1000), le circuit fonctionnel (1000) ayant une fonction élévatrice ; et un sous-circuit de charge (120) destiné à contrôler, sur la base d’une tension d’entrée d’une source d’énergie d’entrée du circuit de protection (100) et d’une tension de sortie du circuit fonctionnel (1000), l’activation ou la désactivation du circuit à haute conduction (110) ; et un circuit accumulateur d’énergie (130) destiné à accumuler la puissance électrique de la source d’énergie d’entrée afin de transmettre la puissance électrique au circuit fonctionnel (1000).
