Title: "Power transfer characteristics during positional misalignment in wireless power transfer using multiple receiving coils"
Application of an underwater wireless power supply system is being considered as a method of charging batteries installed in underwater vehicles, but the power supply position of underwater vehicles tends to shift due to the influence of ocean currents, so it is necessary to consider a stable power supply method. be.In this study, we applied multiple receiving coils to a wireless power transfer system with series resonance on the transmitting side and parallel resonance on the receiving side, and investigated the power transfer characteristics when the receiving coils are misaligned.In particular, we evaluated the stability of the power supply voltage by applying multiple receiving coils by conducting a comparative experiment with the case where there is only one receiving coil.
