一种基于物理的改进型Cauer型IGBT模块热等效电路

A physics-based Cauer-type thermal equivalent circuit (TEC) can be constructed for an insulated-gate bipolar transistor (IGBT) module based on its geometry. In the conventional Cauer-type TEC, each layer of the IGBT module is modeled as a lump with the uniformly distributed temperature. However, this method oversimplified the transient thermal behavior of the IGBT module, leading to unsatisfactory...
