Modeling and Parameter Identification of Underwater Single Capacitor Coupled WPT System

This paper presents a modeling and parameter identification scheme for an underwater single capacitor coupled wireless power transfer (SCC-WPT) system. The scheme estimates the system's parameters and provides theoretical guidance for the system design and control process. An equivalent circuit model of the SCC-WPT system is proposed to implement modeling and parameter identification. Also, the parameter identification method based on reflected impedance is presented in its entirety. Finally, the proposed parameter identification scheme is validated by a 1 kW experimental prototype.
