Evaluation of Capacitive Power Transfer for Small Vessels Charging Applications

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.
