功率模块的瞬态热建模：一种N层傅里叶方法

A transient model of a rectangular N-layer structure with an arbitrary number of rectangular heat sources on the top surface is obtained by Fourier series solution. As power modules can be closely approximated by this type of structure, the model may be used to accurately estimate the temperature field occurring in such modules. The Fourier-based method developed in this work is compared with a fi...
