水下无线输电技术研究综述

Review of Underwater Wireless Power Transfer Technologies

随着人类对海洋资源开发和利用的深入,各种水下观测、通讯、探测设备的应用需求越来越多。使用无线输电技术为水下设备充电,可以克服上岸更换电池和水下有线充电2种传统方法的不足,具有安全、灵活等优点。先后介绍了磁场式、电场式、超声波3种主要的水下无线输电技术,并详细介绍了各系统的典型结构、等效模型和性能特点,进而概述了各种水下无线输电技术的研究现状,指出目前亟待解决的问题,旨在为今后水下无线输电技术的研究提供方向。

With the development and utilization of ocean resources,more and more applications of various underwater observation,communication and detection devices are needed.The use of wireless power transfer technologies to charge the underwater equipment can overcome the shortcomings of two traditional methods(i.e.,on-shore replacement of batteries and underwater wired charging)and has advantages such as safety and flexibility.In this paper,three main types of underwater wireless power transfer(UWPT)technology are introduced successively,which are based on magnetic field,electric field and ultrasonic,respectively.The typical structure,equivalent model and performance characteristics of each system are introduced in detail.Then,the research status of various UWPT technologies is summarized,and the problems to be solved are pointed out,aiming to provide a direction for the future research of UWPT technologies.
