摘要

针对多芯片电力电子系统，提出了一种新颖、精确的动态紧凑热模型提取方法。它考虑了多个热源之间的热耦合。系统设计者很容易考虑到瞬态电热耦合。该方法基于最优热耦合点的定义，即使在瞬态建模中也被证明是有效的。与现有的方法相比，所需的三维热模拟或测量的数量大大减少。

A new methodology for extraction of dynamic compact thermal models

An innovative and accurate dynamic compact thermal model extraction method is proposed for multi-chip power electronics systems. It accounts for thermal coupling between multiple heat sources. Transient electro-thermal coupling can easily be taken into account by system designers. The method is based on a definition of the optimal thermal coupling point, which is proven to be valid even for transient modelling. Compared to the existing methods, the number of needed 3D thermal simulations or measurements is significantly reduced.
