中文摘要

本文提出了一种功率模块的解析建模与优化方法,特别适用于银烧结钼(SSM)封装或其他绝缘金属基板封装。文章首先提出了一种解耦的傅里叶热模型,考虑了基板段之间的热阻隔效应,并与传统模型进行了对比验证。

English Abstract

This article proposes a methodology of analytical modeling and optimization of power modules, especially compatible with modules with silver-sintered molybdenum (SSM) packaging or other insulated metal substrate types of packaging schemes. First, a decoupled Fourier-based thermal model is presented, which considers the barrier effect between substrate segments. Compared with the original Fourier-b...
