Blog Article

Three IGBT short circuit types had been introduced.The short circuit type 2 had been enhanced through optimization of theIGBT transistor gain to withstand higher short Intimate Soap circuit current.Additionally, the IGBT short circuit over current had Gelatin been suppressed by thegate drive clamping design.As a result, the high-voltage IGBT modules had successfully passed the short circuit testes required by tractionapplication.
