用于圆柱形绕组高频变压器高效热预测的多级边界耦合方法

Efficient and accurate thermal prediction is important for the optimal design of high-frequency transformers (HFTs). The configuration of HFTs is typically nonrotationally symmetrical. A 3-D finite-element model (FEM) is utilized for thermal predictions due to its high accuracy. However, its prediction efficiency is unsatisfactory due to three factors. First, the thin wires of HFT windings require...
