在磁耦合无线充电系统中，传输线圈是实现电能高效传输的重要部分，线圈的品质因数直接影响整个系统的效率。为了满足高效率传输的需求，首先通过对串串补偿拓扑系统建立等效电路模型，经理论推导得到线圈传输效率与线圈品质因数的关系，即最大化线圈互感和内阻的比值，实现高效率传输。然后针对线圈设计优化的主要目标：互感与内阻，理论推导其与线圈几何参数之间的关系，深层次提炼为线圈效率与线圈参数之间带约束的多参数最优函数求解问题。最后提出基于粒子群优化算法进行迭代求解，按照求解得到的线圈几何参数绕制不同规格的线圈，测试求解结果的最优性。

In a magnetic coupling wireless charging system, the transmission coil is an important part for improving the efficient transmission of electric energy, and its figure of merit directly affects the efficiency of the whole system. To meet the demand of high-efficiency transmission, first, an equivalent circuit model for an S-S compensation topological system was established, and the relationship between the coil’s transmission efficiency and figure of merit was obtained through theoretical derivation, i.e., maximizing the ratio of the coil’s mutual inductance to its internal resistance can achieve high-efficiency transmission. Then, aimed the mutual inductance and internal resistance which were also the main optimization objectives for coil design, the relationship among the coil’s mutual inductance, internal resistance and geometric parameters was deduced theoretically, and it was further refined into a multi-parameter optimal function problem with constraints between the coil’s efficiency and its parameters. Finally, an iterative solution based on the particle swarm optimization algorithm was proposed, and the winding coils with different specifications were made according to the obtained geometric parameters, so as to test the optimization results.
