Abstract

This paper presents a novel capacitive wireless power transfer (CWPT) approach for electric vehicle (EV) charging, using Harmonic Utilization (Harmion) to enhance efficiency and compactness. Traditional CWPT systems are constrained by limited power transfer efficiency, primarily due to the inherent capacitance limitations of vehicle chassis. This paper introduces an innovative approach leveraging inverter-generated harmonic components to significantly enhance power transfer efficiency. The proposed method not only overcomes traditional limitations but also reduces inductive component requirements, paving the way for more efficient and cost-effective CWPT solutions. The system minimizes inductor size by tuning the LCLC matching network to a specific harmonic component, reducing weight and improving efficiency. Simulations show Harmion reduces inductance requirements by a factor of nine, lowers voltage stress, and ensures safety compliance, making CWPT a viable alternative to inductive charging for fast charging solutions in electrified vehicles of any mode, e.g., vessels.
