摘要

交流电流流过 RLC谐振电路中会出现涡流，线圈电阻也将随交流频率的增加而急剧上升。由于单芯线圈与多芯线圈产生趋肤与邻近效应的机理不同，故两者的交流电阻随交流频率的增加趋势有所不同。采用谐振法测量了单芯线及多芯线中电阻与交流频率的关系，仿真计算了单芯、多芯线圈在不同交流频率下的涡流损耗，表明在高频交流情况下，多芯线圈受涡流效应的影响要高于单芯线圈。同时，实验测试与计算结果相吻合。

Abstract:

Eddy currents oecur when the AC current flows through the RLC resonant cireuit, and the coiresistance will rise sharply as the AC frequency increases. Because the mechanism of skin and proximity effectsbetween single-core coils and multi-core coils is different ,the AC resistance of the two coils is diflerent with theinerease of AC frequeney.T'he relationship between resistance and AC frequency in single-core and multi-corewires was measured by the resonance method, and the eddy current losses of single-core and multi-core coilsunder difflerent AC frequencies were simulated and calculated , which showed that in the case of high-requency AC , the eddy current elfect of multi-core coils was higher than that of single-core coils,Experimental tests are inagreement with the calculated results.

Key words: AC resistance AC frequency skin effect proximity effeet
