Circular Arc Coil Coupling Device for Wireless Charging System of Autonomous Underwater Vehicle

In order to improve the poor fault tolerance ability of coupling device of wireless charging system for autonomous underwater vehicles, a magnetic coupling device with strong fault tolerance ability, low internal electromagnetic interference, and good symmetry is proposed in this paper. Firstly, the magnetic field distribution of the proposed magnetic coupling device is studied by ANSYS Maxwell finite element analysis software. Then, using the method of parameter modeling, the coupling coefficient change of the magnetic coupling device under the dislocation state is obtained. Finally, the circuit structure of the wireless charging system using this coupling device is analyzed and calculated.
