Resonant Wireless Power Transfer over variable distances requires adaptive frequency change in order to preserve efficiency. The Royer oscillator provides the capability of correctly tracking the most efficient resonant frequency without the need of cumbersome control systems. In this paper, a rigorous modeling, including frequency-dependent losses, of a wireless power transfer system based on Royer oscillators is presented and experimentally verified.

Abstract
Resonant Wireless Power Transfer over variable distances requires adaptive frequency change in order to preserve efficiency. The Royer oscillator provides the capability of correctly tracking the most efficient resonant frequency without the need of cumbersome control systems. In this paper, a rigorous modeling, including frequency-dependent losses, of a wireless power transfer system based on Royer oscillators is presented and experimentally verified.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
