Abstract

With the development of wireless power transfer (WPT) technology, it is possible to transfer power to the batteries without plug-in cables and human interaction for autonomous underwater vehicles (AUVs), taking advantage of high safety, high reliability and unattended capability. However, when implementing the WPT system under the seawater environment, the electrical properties of seawater including the permittivity and the conductivity cause a significant changing in the parasitics of winding coils underwater. The seawater, which owns higher permittivity and conductivity compared to the air, not only causes extra parasitic capacitance to coils but also conducts extra eddy current loss, and thus reduces the system efficiency. In this paper, the characteristics of winding coils underwater are investigated and an optimized design methodology for underwater WPT system with series-series (SS) compensation is proposed. A 200-W underwater WPT prototype is built and experimentally verifies the analysis for the coils and the optimized design approach. The experimental demonstration also shows the system efficiency comparison between the air, the water, and the seawater environments.
