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

A circuit modeling technique for the ISO 7637-3 capacitive coupling clamp test [PDF]
, 2018 In this paper, we propose a transmission-line modeling technique for the ISO 7637-3 capacitive coupling clamp (CCC) test. Besides modeling the test bench, special attention is devoted to the CCC itself, for which an equivalent circuit is constructed ...

Constant capacitive wireless power transfer at variable coupling [PDF]
2018 IEEE MTT-S International Wireless Symposium (IWS), 2018 Capacitive wireless power transfer uses the varying electric field for wireless power transfer from a transmitter plate to a receiver plate. The amount of power transferred to the load and the system efficiency are dependent of the coupling between transmitter and receiver.
