Development of Wireless Charging System Robust against Change in Alignment and Load Balance for Long-term Operation of AUVs

Abstract

Although resonant type contactless power feeding devices are suitable for long-term operation of AUVs, there is a problem that the resonance can’t be maintained when the AUV is disturbed by tidal flow or wave. This paper proposes to introduce Q value control to improve efficiency and robustness against alignment and load balance.
