摘要

基于边界元求解法,提出了低压功率MOS晶体管的电、热全耦合三维建模方法。三维热传导和三维电传导之间的类比得到了很好的解释。这两种现象之间的耦合给了我们比温度映射更真实的电压和电流分布。用更简单的方法得到的结果与参考溶液进行了比较。

Non linear 3D electrothermal investigation on power MOS chips
Based on the use of a boundary element solver, a fully coupled electrical and thermal 3D modeling for low voltage power MOS transistors is proposed. The analogy between the 3D heat conduction and the 3D electrical conduction is turned to good account. The coupling between these two phenomena gives us the realistic voltage and current distributions in more than the temperature mapping. Results obtained from simpler approaches are compared to the reference solution.
