Simulation Analysis of Efficiency of Wireless Power Transmission System for AUV

Adequate electrical energy can guarantee long-term navigation for the autonomous underwater vehicle (AUV). Compared with the traditional wired charging method, wireless charging has the advantages of high security, simple operation and so on, and is more suitable for underwater application. In this paper, we study the efficiency of wireless power transmission (WPT) system in air and seawater. The transmission efficiency of wireless transmission system in air and seawater is compared with HFSS simulation. The reason of system efficiency decay is analyzed, which is helpful for the application of wireless power transmission technology in AUV.
