Evaluation of Capacitive Power Transfer for Small Vessels Charging Applications

Abstract

This paper evaluates capacitive power transfer (CPT) with application to the charging of small electric maritime vessels. CPT may provide a cheaper and lighter solution for charging boats with broader safety range and lower eddy losses than inductive charging. The behavior source-based and chain-based equivalent circuit models were used in the analysis. As a case study, the feasibility of charging of the fully electric boat GMV Zero using CPT is considered. The required design parameters needed in order to achieve a similar power level to the conductive charging are analyzed and discussed, where CPT is shown to be a viable solution.
