Perspectives on control strategies for CC-CV charging in Resonant Inductive Power Transfer systems: a review of SS-RIPT configuration

Abstract

This paper explores control strategies for Resonant Inductive Power Transfer (RIPT) systems, focusing on achieving Constant Current Constant Voltage (CC-CV) charging for batteries. Wireless power transfer, particularly via RIPT, is gaining traction for charging Electric Vehicles (EVs), Unmanned Aerial Vehicles (UAVs), and consumer electronics. The study investigates direct and indirect control methods for RIPT systems, concentrating on the series-series RIPT (SS-RIPT) configuration. Through simulations and analysis, the paper showcases the implementation of primary side indirect control for CC-CV charging of Li-Ion batteries, offering insights into its feasibility and effectiveness. The findings contribute to advancing the understanding of control strategies in RIPT systems, facilitating the optimization of charging efficiency and enhancing user experience in wireless charging applications.
