摘要:
针对无线充电技术在电动汽车中的应用,提出了一种新型电力发射系统的设计方法。以矩形线圈和螺旋线圈为研究对象,最终确定采用复合绕组为最佳方案。通过计算单位面积互感系数得到磁通量密度,选择最优匝数和节距以形成均匀磁场,并且运用有限元分析获得发射端偏移容差的性能评估,从而使感应电能传输得到有效提升。模拟出所设计发射端的磁通量密度分布模式,所得结果与预先设计的计算值基本一致。复合结构发射端中,螺旋绕组使用非统一节距时,尽管发射端边缘处磁通量密度不可避免地有所下降,但其它大部分充电区域的磁通量密度仍保持均匀。

Abstract:
To apply the wireless charging technology to an electric vehicle, a design method for power transmitter has been put forward. Rectangular coils and spiral windings are specially selected for evaluation. The compound winding is chosen for optimization. The magnetic flux density is studied by calculating the mutual inductance per area. By optimally choosing the turns and pitch distances of the spiral winding, a uniform magnetic field is achieved. Using finite element analysis, the performances of the transmitter are evaluated, including its tolerance to misalignment, thus effectively improving the inductive power transmission. The magnetic flux density distribution model of the designed transmitting terminal is simulated, and the simulation results are basically consistent with the calculation amount of the pre-designed model. In the transmitting terminal of a compound structure, when the spiral winding adopts non-uniform pitch, although the magnetic flux density at the edge of transmitting terminal is unavoidably reduced, the magnetic flux densities in most other charging areas still remain uniform.
