Development of underwater wireless power supply system using resonant energy transfer

Autonomous Underwater Vehicles (AUV) is one of the key technologies for deep ocean research. However AUV cannot work for long time due to the limitation of battery capacity. To solve this problem, a noncontact wireless power supply is required for AUV to conduct observations for long period. In this study, we developed a resonant energy transfer system, which is mounted into a small AUV “DaryaBird” and the simulations and evaluation tests are carried out in the test tank.
