Abstract :
An existing physics-based insulated gate bipolar transistor (IGBT) model, which has been proven accurate for both inductive turn-off and inductive turn-on simulations, is modified to account for planar-gate IGBT 2-D effects at the MOS end of the drift region. The modification is based on a steady-state solution of carrier distribution in the JFET region of the IGBT. The accuracy of this solution is verified through a set of finite element simulations. The improved accuracy of the modified model in terms of on-state forward drop and voltage tail at turn-on is verified through comparison with experimental results.
