Design Considerations for a Position-Adaptive Contactless Underwater Power Deliver System

Abstract

With the understanding and development of the ocean, the Deep-sea exploration technology has become a hot spot of research in many countries. As the most promising underwater power feeding technique, contactless power transmission extends the working range of underwater detection equipment. The classic equivalent circuit model is modified to include the eddy current loss in seawater. Considering the waterflow effects, a coaxial 300W position-adaptive contactless underwater power deliver system is designed and optimized in this paper. Experimental results validate the theoretical analysis in this paper.
