WebIGBT. If the short circuit is applied to an IGBT that is already conducting, the dv/dt resulting from the rapid de-saturation of the IGBT would boost the gate voltage of the IGBT and results in higher peak SC current (Fig 5 & 6). The increased peak current would increase the power dissipation and could cause IGBT failures. WebThe problem is that the IGBT is failing a lot, the collector-emitter is completely shorted. Its probably caused by a voltage spike at turn off. I cannot capture it exactly as fails randomly. The IGBT in question does not have a built in diode.

WebI think there may be two reasons. First, here's a transistor that is specified for use in ignition systems and note that it has a protection circuit built in that will turn the transistor back on (thus protecting itself) if the voltage at the collector exceeds 350V. Web5 mei 2010 · May 3, 2010. #6.
