中文摘要:

针对水下自主航行器无线充电系统在复杂环境中易产生偏移、传输功率与效率不稳定的问题，提出了一种抗偏移性能优异的磁感应耦合式无线充电系统。通过磁芯与线圈结构设计，优化了磁路走向，与现有结构相比，在空间占用、磁场约束及抗偏移性能方面更优。同时选择了补偿网络，使用受控源模型分析恒流输出性能，通过ZVS方法进行参数设计，降低额外损耗。仿真结果表明，该无线充电系统在横向偏移20 mm及纵向偏移15 mm时，耦合系数衰减在20%以内，在旋转偏移15°时耦合系数衰减在15%以内。在负载增大10倍时输出电流波动保持在10%以内。制作了磁耦合结构，各方向偏移时耦合系数衰减均保持在25%以内。进行了硬件实验，样机传输效率为83%，在各方向偏移时传输功率均保持在最高功率的70%以上，传输效率保持在70%以上。

英文摘要:

To address the issues of misalignment and unstable transmission power and efficiency in complex environments for Autonomous Underwater Vehicle wireless charging systems, a magnetic induction coupling wireless charging system featuring high misalignment tolerance is proposed. The magnetic core and coil structures are designed to optimize the magnetic path. Compared with existing systems, it has better space efficiency, magnetic field control, and anti-misalignment performance. A compensation network for the system is selected based on anti-misalignment performance. The constant current output performance is evaluated through controlled source model. The ZVS method is applied in parameter design to minimize extra losses. Simulation results show that the wireless charging system maintains coupling coefficient attenuation within 20% for lateral offsets of 20 mm and longitudinal offsets of 15 mm, and within 15% for rotational offsets of 15°. The output current fluctuation remains within 10% when the load is increased by ten times. The magnetic coupling structure was fabricated, and the coupling coefficient attenuation remains within 25% under misalignment in all directions. The hardware experiment was conducted, with experimental results showing 83% transmission efficiency at 10 Ω load with 25 V input voltage. When subjected to maximum design-range offsets in various directions, the system maintains transmission power above 70% of its peak value while sustaining transmission efficiency exceeding 70%.
