摘要:
基于结构函数理论,对同一管壳与基板的不同界面热性能进行研究,发现积分结构函数曲线出现分离, 通过分离点可确定IGBT 模块内部PN 结与基板外壳之间的热阻值;通过此方法,还可确定同一管壳采用不同接触 面材料的热特性,并可依此对IGBT 所用涂覆导热材料进行选型。研究表明,结构函数理论是分析大功率IGBT 器 件热特性的一种有效方法。
Abstract:
Based on the structure function theory, it studied the thermal characteristics between the same IGBT case and the different baseplate interfaces, and found separation point of structure functions, by which thermal resistance between the internal PN junction and the case of IGBT module was got. Besides, through comparing the structures of IGBT module with different contact materials, the proper contact material was selected. The study results show that the structure function is a powerful method to analyze the thermal characteristics of high power IGBT modules.
