| 摘 要： | 在集成门极换流晶闸管(IGCT) 2T-3R-C 电学模型的基础上，针对其模型关断电压出现与实测波形不
符的振荡问题，建立了一种 IGCT 改进电学模型，并提出一套可用于改进电学模型的参数提取方法，给出改进电
学模型电路结构和器件参数。将模型的动态特性仿真结果与 4kA/4.5kV 型号 IGCT 的 4kA/4.5kV 等级实验结果、
3.5kA/4.5kV 等级实验结果以及现有 2T-3R-C 模型仿真结果进行对比，验证了改进电学模型的准确性、适用性、
优越性。

| Abstract: | An improved electrical model of the Integrated gate-Commutated Thyristor (IGCT) was
established on the basis of the 2T-3R-C electrical model to solve the oscillation problem that the turn-off voltage
of the model was inconsistent with the measured waveform, and a set of parameter extraction methods suitable for
the improved electrical model was proposed. The simulation results of dynamic characteristics of the model were
compared with the experimental results of 4kA/4.5kV and 3.5kA/4.5kV at the same voltage level and different
current levels, as well as the simulation results of the existing 2T-3R-C model. The accuracy, applicability and
superiority of the improved electrical model are verified. |
