Based on the existing ideal Hardware-in-the-loop ( HIL) real-time simulation model of voltage source type three-phase bridge type inverter, the HIL real-time simulation model of IGBT loss and temperature rise was established. The model was set up on the HIL platform based on field programmable gate array ( FPGA) . Using data sheet with linear interpolation method, IGBT loss model was established. By adopting the method of equivalent thermal network circuit, IGBT temperature model was established. Also according to the structural parameters of radiator, the thermal resistance was calculated to enhance the applicability of the model. In order to extend the practical value of model, the PC communication design using LabVIEW was carried on, realizing real-time input function of the model parameters and the function of model data real-time acquisition and transmission to the PC interface to display. At the end, the real-time HIL simulation model was compared with the MATLAB simulation model to validate the data accuracy of the model, and compared with actual test to verify the reliability of the model.%在现有电压源型三相桥式逆变器的理想硬件在环( HIL)实时仿真模型的基础上,建立了IGBT损耗及温升的HIL实时仿真模型. 模型是在基于FPGA的HIL平台上搭建. 采用数据手册结合线性插值的方法建立了IGBT损耗模型. 采用等效热网络电路方法,建立了IGBT温升模型. 同时也可根据散热器结构参数计算热阻,增强了模型的适用性. 为了扩展模型的实用性,采用LabVIEW进行了上位机通信设计,实现了模型参数实时输入功能,以及模型数据实时采集并传输到上位机界面显示功能. 最后将MATLAB仿真模型与HIL实时仿真模型进行对比,以验证模型的数据精度,并与实物测试进行对比,以验证模型的可靠性.
