The invention discloses an IGBT module state monitoring device and method. The device comprises an IGBT module, a gate turn-on voltage overshoot monitoring module, a driving circuit, a bonding wire state judgment module and a signal acquisition module; and monitored actual gate turn-on voltage overshoot is compared with a preset reference gate turn-on voltage overshoot threshold value, so that thebreaking condition of a bonding wire is obtained. With the IGBT module state monitoring device and method of the invention adopted, the monitoring problem of the aging of the bonding wire of an IGBTin a power electronic converter is solved; the falling off of the bonding wire is characterized by the gate turn-on voltage overshoot; and therefore, invasion to a circuit can be avoided, and the slight aging monitoring of the falling off of the bonding wire can be realized. The IGBT module state monitoring device and method have the advantages of high resolution, no invasion, real-time on-line monitoring, high sampling frequency and low cost, and is of great significance to the monitoring of IGBTs and the reliability evaluation of power electronic converters.
