摘　　要：本文提出了用于模拟ＧＴＯ关断特性的ＳＰＩＣＥ等效电路模型．根据器件的工作特性并结合器件结构提取模型参数．用此模型对１０００Ａ／２５００Ｖ阳极短路型ＧＴＯ的关断特性进行了模拟，包括关断电流拖尾现象在内的整个关断过程，模拟结果与器件的测试结果吻合较好．Abstract A new model for SPICE simulation of the turn off process in GTO is presented to resolve the problem that the earlier models can not be used to simulate its current tail precisely because of their default of the function to describe the charge transmission in the turn off process of GTO. The new model is successfully used to simulate the turn off performance of a 1000A/2500V anode short GTO device. As a comparison, simulation with the earlier model is also carried out for the same device. It is evident that the current tailing is appeared in the plot from the new model and disappeared in the plot from the earlier model. Comparing to the test data of the same device, the simulation results is precise enough to ensure a precise circuit design.
