[Title of award-winning research]
Power transmission characteristics of wireless power supply for underwater probe using three sets of power transmission circuits

[Details of award-winning research]
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 conducted an experiment to examine the effect of applying resonant frequency tracking control to wireless power supply for an underwater vehicle, which has three sets of power transmission circuits that can detect the positional deviation of the underwater vehicle. The improvement in power transmission efficiency was confirmed through experiments.
