Abstract

In this paper, we report the design and the optimization of high-quality-factor self-resonant coils for Wireless Power Transfer (WPT) relying on resonant inductive coupling. The main benefit of self-resonant coils is their potential to increase the quality factor of WPT systems, enabling to reach higher efficiencies at large distances. An analytical modeling of self-resonant coils is proposed and validated by finite element simulations (ADS Keysight). Self-resonant coils prototypes are then introduced and characterized, and a new topology for impedance-matched self-resonant coils enabling to further increase the performances of WPT systems is finally reported.
