The study of extending navigation range of autonomous underwater vehicles (AUVs) is popular for ocean exploration. A common method is to use the underwater docking station to recover and recharge AUVs. This paper uses the simple but effective inductive power transmission (IPT) system to realize underwater wireless charging for an AUV docking system. A design procedure is provided to select the optimal underwater operating frequency of the IPT system in consideration of eddy-current loss in seawater. To solve the power failure problem of the control power system, an inrush current limiter (ICL) is proposed on the basis of the dynamic model of the IPT system. The test results in the laboratory experiment and sea trial both verify the advantages of the frequency design method and the effectiveness of the ICL.

改善AUV对接系统无线充电的稳启动特性

扩大自主水下航行器 (AUV) 导航范围的研究在海洋探索中很受欢迎。一种常见的方法是使用水下坞站对 AUV 进行恢复和充电。本文采用简单而有效的感应电力传输（IPT）系统为AUV对接系统实现水下无线充电。考虑到海水中的涡流损失，提供了一个设计程序来选择 IPT 系统的最佳水下工作频率。为解决控制电源系统的停电问题，在IPT系统动态模型的基础上，提出了一种浪涌电流限制器(ICL)。室内试验和海试的测试结果均验证了频率设计方法的优点和ICL的有效性。
