Abstract (in Japanese) (See Japanese page) 
(in English) Practical application of wireless power supply, which can supply power even in seawater, is expected to extend the operating time and range of underwater mobiles such as AUVs (Autonomous Underwater Vehicles). We have developed a magnetic field coupling type power transmission system with 2 m diameter series of three transmission coils and have demonstrated that wireless power transmission of 3 kW to an AUV is possible in actual sea areas. This system has the advantage to keep high efficiency, even if receiving coil move anywhere inside the transmission coil.
