An overcurrent protection circuit for a power switching transistor wherein the power switching transistor has a control electrode and two main electrodes, the circuit comprising a circuii including a protection switch for sensing the rate of change of voltage with respect to time at one of the main electrodes of the power switching transistor and for controlling the protection switch to remove a control signal to the control electrode of the power switching transistor to turn off the power switching transistor if the rate of change exceeds a predefined value.
L'invention porte sur un circuit de protection contre les surintensités d'un transistor de commutation d'une alimentation présentant une électrode de commande et deux électrodes principales. Ledit circuit comprend: un circuit à commutateur de protection détectant la vitesse de variation de la tension sur l'une des électrodes principales du transistor, et actionnant le commutateur de protection pour supprimer un signal sur l'électrode de commande du transistor et le mettre hors tension si la vitesse de variation dépasse un seuil prédéfini.
