Abstract

L’invention se rapporte à un dispositif de protection de transistor de puissance (DUT), pouvant être connecté d’une part à une grille (G) d’un transistor de puissance (DUT), et d’autre part à un amplificateur de puissance (AP) configuré pour fournir un courant de grille (Ig) suffisant pour faire commuter le transistor de puissance (DUT), le dispositif comprenant au moins une résistance (Rg), et un détecteur (DET) comprenant un premier comparateur de tension (U4) configuré pour détecter une consommation anormale de courant de grille (Ig) après une séquence de commutation du transistor de puissance (DUT) lors de son amorçage, et comprenant un second comparateur de tension (U5) configuré pour détecter une génération anormale de courant de grille (Ig) pendant une séquence de conduction du transistor de puissance (DUT) dans son régime faiblement ohmique.
