| 摘 要： | 变压器损耗是影响变压器运行性能的重要因素。在高频效应下,邻近效应与集肤效应会增加变压器绕组损耗。文章基于高频变压器绕组的三维模型,在考虑邻近效应与集肤效应的基础上,应用有限元法对变压器绕组中的涡流效应进行仿真计算。通过计算得出了改变绕组布局可以有减少绕组损耗的结论。并得到了不同绕组布局下,绕组损耗随频率、绕组厚度以及层间距的变化趋势。

| Abstract: | The transformer loss is the important factors influencing the operation of transformer.The high frequency eddy effects including skin and proximity effects will raise the winding losses.The eddy current effects are calculated by the finite element method, in consideration of proximity effect and skin effect.The conclusion that changing wind-ing layout can decrease the winding losses is given.The tendency of the losses caused by skin effect and proximity effect under different winding thickness, frequency and layer spacing is concluded. |

| Keywords: | high-frequency transformer proximity effect skin effect FEM winding losses |
