  • By applying wireless charging technology, the autonomous undersea vehicle (AUV) can be made into a fully enclosed structure to avoid corrosion in seawater and eliminate the risk of leakage of electricity. In order to solve the electromagnetic interference problem that may exist in the AUV wireless charging process and optimize the coil structure, an AUV wireless charging system with improved coil structure is designed, which can be used in AUV charging device. Simulation results in ANSYS MAXWELL show that the proposed coil structure can make the coupled magnetic field mainly distributed in the vicinity of the AUV casing, minimizing the influence on the internal components of the AUV, and maintaining the mutual inductance stability even when the rotational offset occurs. Experimental results show that the output voltage fluctuation of the built-in wireless charging device is less than 10% in the condition of rotational offset, and the efficiency is about 70% for transmitting 40 W of electric energy.
