Optimal Coupling for Capacitive Wireless Power Transfer with One Repeater
2022 52nd European Microwave Conference (EuMC), 2022 Abstract: In order to extend the range of capacitive wireless power transfer, an electric field repeater between transmitter and receiver can be applied. In this work, a network formalism is adopted to analytically describe and maximize the system efficiency of a repeater setup. The resonator components, resistive losses, load and supply impedances are

Optimum Receiver-Side Tuning Capacitance for Capacitive Wireless Power Transfer [PDF]
Electronics, 2019 This paper reveals the optimum capacitance value of a receiver-side inductor-capacitor (LC) network to achieve the highest efficiency in a capacitive power-transfer system. These findings break the usual convention of a capacitance value having to be chosen such that complete LC resonance happens at the operating frequency. Rather, our findings in this
