| 摘 要： | 在低压大电流DC-DC模块电源中，经常使用并联绕组。由于电磁场的高频效应 (集肤和邻近效应)，可能导致电流在各并联绕组层中不均分，产生较高的交流电阻。本文提出使电流在各并联层中均分的绕组布置方法。并通过有限元分析软件和实验证实了所提出的绕组布置方法的正确性和有效性。

| Abstract: | Using parallel windings is a very common practice in low voltage and high current DC-DC converters. Because of high-frequency effects (namely skin and proximity), the current flowing through those windings is not equally divided among them, resulting in high ac resistance. This paper discover a way for winding arrangement which make current share in the paralleling windings. Using Finite Element Analysis (FEA) and test prove its correction and effectiveness. |

| Keywords: | planar transformer parallel windings ac resistance winding arrangement |
