Title (EN) OVERCURRENT PROTECTION DEVICE AND METHOD OF OPERATING A POWER SWITCH
(FR) DISPOSITIF DE PROTECTION CONTRE LES SURCHARGES ET PROCÉDÉ DE FONCTIONNEMENT D'UN COMMUTATEUR D'ALIMENTATION
Abstract: front page image
(EN)An overcurrent protection device (18) comprises a maximum-allowed-current unit (34) and a power switch (20) having a conductive state and a nonconductive state. The maximum-allowed-current unit (34) determines a time-dependent maximum allowed current (I1; I2) according to a supply voltage. The power switch (20) assumes the nonconductive state in response to an indication that a current through the power switch (20) is exceeding the maximum allowed current (I1, I2). A method of operating a power switch (20) is also described.
(FR)La présente invention concerne un dispositif de protection contre les surcharges (18) qui comprend une unité de courant maximal autorisé (34) et un commutateur d'alimentation (20) possédant un état conducteur et un état non conducteur. L'unité de courant maximal autorisé (34) détermine un courant maximal autorisé dépendant du temps (I1; I2) en fonction d'une tension d'alimentation. Le commutateur d'alimentation (20) adopte l'état non conducteur en réponse à une indication selon laquelle un courant traversant le commutateur d'alimentation (20) dépasse le courant maximal autorisé (I1, I2). L'invention concerne également le fonctionnement d'un commutateur d'alimentation (20).
