Three IGBT short circuit types had been Anchors introduced.The short circuit type 2 had been enhanced through optimization of theIGBT transistor gain to withstand higher short circuit current.Additionally, the IGBT short circuit over current had been suppressed by thegate drive clamping design.

As a result, the high-voltage IGBT modules had successfully passed the short Laptop Sleeves circuit testes required by tractionapplication.
