IGBT驱动参数评估十一-开通VGEmin

4.3 IGBT驱动负栅极电源电压的变化 IGBT模块开通过程的影响
类似于IGBT的关断过程，变化的负栅极电压主要会影响开通过程的延迟时间。反向恢复电流的di/dt，及dv/dt保持在同一水平。转载请注明出处 http://www.igbt8.com

The manufacturer often recommends the use of negative gate voltage to safely turn-off and block IGBT modules. In areas with nominal currents less than 100tA the negative gate voltage is often omitted for cost reasons. The following paper describes special considerations for a unipolar drive of IGBT modules.

Max(C2): 26.25, Max(C3): 203A, Max(C4): 383V
