电流增益与IGBT的开通及关断特性

Characteristics of Current Gain With Forward Drop and Turn off Time on IGBT

阐述了关于协调ＩＧＢＴ通态压降和关断时间的最佳关系。在工艺过程中，控制双极晶体管电流增益αｐｎｐ的最佳值，就可调整通态和关断特性的相互关系。

In this paper,the optimum interrelation coordinated in forward drop and turn off time of IGBT is presented.In process,it is important to control the α pnp of bipolar transistor for conditioning interrelation of on state and turn off characteristics.
