Analysis of effect of interleaving techniques on winding loss of high-frequency tranformer based on ANSYS simulation

为了探究绕组交叉换位对高频变压器绕组损耗的影响,基于高频变压器样机模型,利用ANSYS有限元软件建立了高频变压器的仿真模型,并考虑了高频下绕组的集肤和临近效应的影响,然后对比分析了绕组交叉换位前后磁心窗口内的磁感应强度、绕组电流密度分布以及绕组损耗的变化规律,得出了绕组交叉换位可以有效降低绕组损耗的结果。同时也说明了利用ANSYS软件分析高频变压器模型损耗的合理性和有效性,为高频变压器的优化设计提供了有效技术支持。

In order to explore the effect of interleaving technique of winding on winding loss of high frequency transformer,based on the high frequency transformer prototype model,the finite element software of ANSYS is used to establish the simulation model of high frequency transformer,and the uninterleaving winding is taken in constrast with interleaving winding in the aspects of magnetic flux intensity of the magnetic core window,current density distribution of winding and winding loss. In conclusion,the interleaved winding technique can reduce winding loss of high-frequency transformer,at the same time the simulation by ANSYS verifies the rationality and feasibility of loss analysis of the winding structure,and this provides effective technical support for optimum design of high-frequency transformer.
