Abstract:
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 calcu-lation method was proved by the consistency of the experimental results and the formula programming cal-culation results under the condition of different space positions such as different axial distances,radial dis-tances and rotation angles between the coupling coils.
