摘　　要：磁耦合谐振式无线电能传输技术通过空间分离线圈之间的电磁耦合实现电能的无线传递,耦合线圈尺寸的不同和相对位置的变化会引起线圈间的互感变化,继而影响无线电能传输系统的特性。以常见的矩形截面空心线圈为分析对象,对任意空间位置线圈间互感的计算方法进行研究,通过纽曼公式和细分求和法推导了互感的理论计算公式,为静态和动态无线电能传输系统的设计提供支持。在耦合线圈具有不同轴向距离、径向偏距及旋转角度等空间位置情况下,公式编程计算和实验测量结果都具有一致性,证明了计算方法的正确性。The magnetic coupling resonant wireless power transfer technology realizes the power transfer wirelessly by means of electromagnetic coupling between space-separated coils. The different sizes and relative position change of coupling coils may cause the mutual inductance magnitude variation, which can thereby influence the performance of wireless power transfer system. Taking the common rectangular cross section air-core coils as the analysis object, the calculation method of mutual inductance between arbitrary space positioned coils was researched and the relevant theoretical formula was derived based on Neumann equation and method of subdivision and superposition. The calculation formula can give the support to the design of both static and dynamic wireless power transfer systems. The correctness of the proposed calculation method was proved by the consistency of the experimental results and the formula programming calculation results under the condition of different space positions such as different axial distances, radial distances and rotation angles between the coupling coils.
