Maximizing the Power Transfer for a Mixed Inductive and Capacitive Wireless Power Transfer System [PDF]
2018 IEEE Wireless Power Transfer Conference (WPTC), 2018 Nowadays, near-field wireless power transfer is realized by inductive or capacitive coupling. Power transmission is respectively accomplished by a time-varying magnetic or electric field as medium. Recently, mixed or hybrid near-field wireless power transfer is being developed as a possible mean to increase the power density of the system by utilizing ...

Capacitive power transfer through virtual self‐capacitance route
IET Power Electronics, 2018 This study presents the modelling, analysis, and experimental results of a novel capacitive power transfer (CPT) structure with a single coupling capacitor. It is noticed that each charged object has a nature property called self‐capacitance, which is a kind of capacitance with respect to infinity.
