Capacitive Wireless Power Transfer System Applied to Low-Power Mobile Device Charging

Wireless Power Transfer (WPT) technologies are most popularly based on inductive coupling (IPT), using magnetic fields as transfer interface. Recently, studies have been published on capacitive coupling (CPT), through electric fields. CPT has small power density, due to low coupling capacitance, however, it also features reduced EMI shielding requirements, coupling through metal barriers, simpl...

Dynamic Charging of Electric Vehicles by Wireless Power Transfer

I N RECENT TIMES, wireless power charging of electric vehicles (EV) has gained huge attentions. Static wireless charging for EVs has seamlessly been achieved using the inductive power transfer (IPT) technology. More recently, dynamic (also termed in-motion) wireless charging with IPT technology has been successfully demonstrated for electric mass transportation means like electric trains, trams...

Design of a Wireless Capacitive Power Transfer System

This paper presents the design of a capacitive power transfer (CPT) system by using the Class-E amplifier approach. The Class-E amplifier approach is chosen to be adopted since it produces high efficiency as close as to 100%, theoretically. Based on the Class-E approach, a design of wireless power transfer system is used to transfer power to a LED lamp. The system has an output around 4.2 watts...
