摘要: 为提高SiC灭磁电阻能容量评估计算的科学性和准确性,基于所研究开发的一套SiC灭磁电阻离线测试系统和配套检测项目,分析和研究了大能量注入、温度红外成像、多组件均能等离线检测项目数据及其参数计算方法。新定义了“散热反系数”来修正由于散热和热量均衡等不可测物理过程对计算结果的影响,总结出了基于离线检测数据并参考制造厂设计参数的一整套SiC灭磁电阻能容量综合计算评估方法。最后,还分析了影响计算评估结果准确性的因素,并提出了相应的对策建议。

Abstract: In order to improve the evaluation accuracy of the SiC de-excitation resistance energy capacity, the testing data of macro-energy injection, infrared imaging and average energy of multiple components are analyzed based on a novel off-line testing system of SiC de-excitation resistance and its relevant testing items. A new parameter“heat dissipation reciprocal coefficient” is defined to revise the impacts of unpredictable physical processes such as heat dissipation and equalization on the calculating results. A set of methods are proposed for comprehensive evaluation of the SiC de-excitation resistance energy capacity based on the off-line testing data and with a reference to the manufacturer’s design parameters. Finally, the influencing factors of the proposed evaluation method are analyzed and corresponding measures are proposed.

Key words: de-excitation, SiC resistance, energy capacity, heat dissipation reciprocal coefficient, evaluation
