Analysis of Harmonics in Wireless Power Transmission System
Fundamental wave approximation (FHA)has been widely used in loose coupling radio power transmission (WPT)systems.However,due to the existence of higher-order harmonic components in strongly coupled systems,FHA can affect the analysis accuracy.Thus this paper proposes an accurate analysis method for strongly coupled WPT systems and derives an output expression that considers the contribution of harmonic components.The effectiveness of this method has been verified by both simulation and experimental results.
