摘　　要：自动水下航行器(AUV)续航问题限制了自身的发展,故设计一种合理的供电方式来提高其续航能力十分必要。感应耦合是非接触式电力传输的常用方法,在水下传输电能过程中具有较高的安全性和可靠性。这里提出了一种初级圆筒式次级条幅阵列式磁芯的耦合结构用于AUV的无线充电,且该结构与船体外形兼容性较强。在海水环境中,研究了其涡流损耗特性。仿真与实验结果证明,该结构较同轴无芯线圈结构,输出功率显著提高,涡流损耗较低,海水中电能传输具有一定的优越性。The endurance problem of automatic underwater vehicle(AUV) limits its own development,so it is necessary to design a reasonable power supply method to improve its endurance.Inductive coupling is a common method of non-contact power transmission,which has high safety and reliability in the process of underwater power transmission.Therefore,a coupling structure of a primary-side cylindrical and secondary-side banner array magnetic core for wireless charging of AUVs is proposed,and the structure has strong compatibility with the shape of the hull.In seawater environment,its eddy current loss characteristics are studied.Simulation and experimental results show that the structure has significantly higher output power and lower eddy current loss than the coaxial coreless coil structure,and has certain advantages for power transmission in seawater.
