摘要如何对电磁线圈进行合理的设计及优化是无线电能传输系统设计时需要解决的关键问题之一。本文提出了无线电能传输系统的直接场路耦合算法模型, 并通过参数求解的方法计算了不同半径的单匝线圈空间磁场及电路参数的整体变化趋势, 从而得出与线圈设计相关的指导原则。然后根据大功率电磁耦合谐振式无线电能传输系统的特点设计了三种不同结构发射线圈, 计算了电气特性并通过实验进行验证。实验结果表明, 五组并绕盘型线圈与其他结构线圈相比具有更低的电感量与更高的谐振频率, 并且实际工况下中心轴向磁场强度与沿轴向磁场较大, 适合作为发射线圈形式。通过采用本文分析方法可有效避免设计和试验的盲目性。

Abstract：How to design and optimize the electromagnetic coils reasonably is one of the key questions that need to be solved when design a wireless power transmission system. In this paper, a direct field-circuit coupling model is proposed. The overall trend of magnetic field in space and electrical parameters in circuits are simulated so that guiding principles about coil design are obtained. Then according to the characteristics of high power electromagnetic resonant coupling system, coils with different structures are designed, simulated and validated by experiments. It is shown that disc shaped parallel winding coil has a lower inductance and a higher resonant frequency than the other two types. And it is more suitable working as the transmitting coil form that magnetic field strength is higher on the central axis direction and radial direction. Meantime, the blindness of design and test can be avoided by using the method.

Key words： Wireless power transmission field-circuit coupling transmitting coil disc shaped parallel winding coil
