| 摘 要： | 文中提出了一种新型的利用通态V_(ce-on)实时估测结温的方法。首先分析了被测IGBT模块通态V_(ce-on)与温度的相关性,然后通过软件提取了模块的互连材料参数,该方法大大降低了实验成本,操作也更加简便。最为重要的是,充分考虑了内部材料电阻对IGBT模块结温的影响,并对其进行了补偿。最后,通过比较红外摄像仪测量结果和实时估测结温验证了该方法的有效性。

| Abstract: | a novel method for real-time estimation of the junction temperature using on-state Vce-on is proposed in this paper. The dependence of temperature on the Vce-on in IGBT module is analyzed firstly, and the parameters of the interconnection materials are extracted using simulation software, which greatly reduces the experimental cost and the operation is easier. Most importantly, the influence of interconnection material resistance on IGBT module is fully taken into account , and compensation is given. Finally, this paper proves the validity of the method by comparing the measurement results by infrared camera with the estimation results by proposed method. |
