针对电动船舶充电应用的无线充电技术逐渐受到关注，由于电动船舶无线充电传输距离较大，磁耦合机构的耦合系数和抗偏移能力会随着传输距离的增大而急剧减少，从而降低传输效率和输出功率。提出1种日字螺线管磁耦合机构，并搭建不同结构的磁耦合机构的有限元仿真模型对其性能进行对比；同时对提出的日字螺线管磁耦合机构进行优化，设置相应的磁屏蔽装置，与传统螺线管相比磁心使用减少了32%，利兹线使用减少了38%，有效地提高了磁耦合机构的耦合系数和抗偏移能力。最后搭建了1套无线充电样机，其传输效率可以达到88%，实验与仿真结果一致。

Abstract

The wireless charging technology for electric boats charging applications has gradually attracted attention. Due to the long wireless charging transmission distance of electric boats, the coupling coefficient and anti-misalignment capability of a magnetic coupler will decrease sharply with an increase in the transmission distance, thus reducing the transmission efficiency and output power. A novel solenoid magnetic coupler is proposed, and the finite element simulation models of magnetic couplers with different structures are built to compare their performance. In addition, the proposed solenoid magnetic coupler is optimized, and the corresponding magnetic shielding device is configured. Compared with those of the traditional solenoid magnetic coupler, the use of magnetic core and Litz wires of the novel solenoid magnetic coupler are reduced by 32% and 38%, respectively, thus effectively improving its coupling coefficient and anti-misalignment capability. Finally, a set of wireless charging prototype was built, and the transmission efficiency can reach 88%. The experimental results were consistent with the simulation results.
