要約(英語): This paper discusses the relationship between resonant frequency and load voltage in wireless power transfer (WPT) systems using series and parallel resonant capacitors and proposes a method to express the resonant frequency using an attenuation coefficient. The resonant frequency and load voltage are derived theoretically by using a simple equivalent circuit when the quality factor of the resonant circuit is low. The resonant frequency expressed by the attenuation coefficient can be used to indicate points of similarity of the resonant frequency in each WPT system. Experimental resonant frequencies agree well with their theoretical values and demonstrate voltage-source and current-source operation at the load side.
