Abstract

Un circuito ed un metodo per il rilevamento e la protezione da una condizione di sovracorrente in un dispositivo di commutazione a transistore di potenza, e particolarmente in un transistore IGBT (Insulated Gate Bipolar Transistor).Il dispositivo di commutazione a transistore di potenza ha i terminali principali ed un terminale di controllo, i terminali principali avendo una tensione dì saturazione normale fra essi durante la conduzione normale del dispositivo a transistore di potenza.Il circuito comprende un circuito di controllo che fornisce segnali di controllo al terminale di controllo del dispositivo a transistore di potenza per la commutazione del dispositivo di potenza nello stato di accensione e spegnimento (on/off), un circuito di rilevamento accoppiato con il dispositivo a transistore di potenza per rilevare la tensione di saturazione del dispositivo a transistore di potenza, ed un circuito di commutazione accoppiato con il terminale di controllo del dispositivo a transistore di potenza che è sensibile al circuito di rilevamento per l'eliminazione dei segnali di controllo dal terminale di controllo nel caso che la tensione di saturazione raggiunga un livello e che indica una condizione si sovracorrente nel dispositivo a transistore di potenza (Fig. 2).
