Abstract: For solving the energy supply problem of underwater equipment, underwater wireless power transfer technology is becoming a new type of underwater power transfer mode. It has the incomparable technical advantages of traditional battery replacement or wet-mate connectors, which can effectively improve the safety, convenience and concealment of underwater charging. This article reviews state-of-the-art wireless power transfer solutions for underwater applications. Then, the docking system, compensation topology, and magnetic coupler types are studied in detail based on the analysis of the principle of underwater wireless power transfer technology. Furthermore, the differences of wireless power transfer technology between marine environment and air are compared, while the research hotspots and potential challenges in the current research progress are summarized. In addition, based on the possible technical development trends, the authors envision the technology prospects on the stance from the prototype to products, followed by some conclusions and constructive advice.
