摘　　要：以大功率逆变器为例子,根据损耗器件自身特点和后期样机现有老化测试条件,寻找最能体现各损耗器件热性能的典型温度点。在产品研发前期阶段,利用Icepak热分析软件对逆变器整机方案进行热分析,并对各个损耗器件的典型温度进行控制;在后期样机老化测试阶段,对相应的典型温度进行测试,并采用忽略背景温度辐射影响的温升对比方法对热分析的精确性进行评估。通过产品研发阶段对典型温度的控制,在不增加老化测试设备成本的基础上使得热分析结果具备合理性,从而提高了整机热分析精度。Taking the high-power inverter as an example, this paper explores to find the typical temperature points to best reflect each loss component＇s thermal performance based on its inherent characteristics and the aging test conditions of the sample inverter. In the early stage of product development, make thermal analysis of the whole inverter scheme using Icepak thermal analysis software, and control the typical temperature of each loss devices in the later stage of the prototype aging test, record the corresponding typical temperature and assess the thermal analysis accuracy by ignoring the influence of background radiation of ambient temperature. By control the typical temperature in the product development phase, without increasing the testing equipment cost, make the thermal analysis results reasonable, thus improving the overall accuracy of thermal analysis.
