| titleOfInvention | IGBT module state monitoring device and method |
| abstract | The device comprises an IGBT module, a grid opening voltage overshoot monitoring module, a driving circuit, a bonding wire state judging module and a signal acquisition module, wherein the situation of the breakage of a bonding wire is obtained by comparing the monitored actual grid opening voltage overshoot with a preset reference grid opening voltage overshoot threshold value. The invention solves the problem of aging monitoring of the bonding wire of the IGBT in the power electronic converter, represents the falling of the bonding wire by using the overshoot of the grid opening voltage, has no invasion to the circuit, can realize slight aging monitoring of the falling of the bonding wire, has high resolution, no invasion, real-time online monitoring, high sampling frequency and low cost, and has important significance for the monitoring of the IGBT and the reliability evaluation of the power electronic converter. |
