摘要
在已有的绝缘栅双极性晶体管(insulated gate bipolar transistor,IGBT)机理模型的基础上将IGBT分为金属-氧化层-半导体-场效晶体管(metal oxide semiconductor field effect transistor,MOSFET)和双极结型晶体管(bipolar junction transistor,BJT)2部分,分别对其进行建模,同时给出了模型参数的提取方法。模型在Matlab中实现。以FZ600R65KF1型IGBT为例给出了模型参数值,并完成了该型号IGBT的单管测试实验。通过对高压IGBT开通暂态、关断暂态和开关损耗的仿真结果和实验结果进行比较,验证了机理模型对于高压IGBT的适用性。
Insulated gate bipolar transistor (IGBT) physical models were studied to divide the IGBT into metal oxide semiconductor field effect transistor (MOSFET) and bipolar junction transistor (BJT) parts. A high voltage IGBT transient physical model was presented. The parameters extraction method was also given. The model in Matlab was tested in a Buck converter using FZ600R65KF1 IGBT with its parameters provided. By comparing the experiment and simulation results of voltage, current and powerloss waveforms during turn on and turn-off transient, the accuracy of the transient model of high voltage IGBT is verified.
