Safe Charging for Wireless Power Transfer

Optimal Battery Charging Methods for Wireless Power Transfer

Introduction Rechargeable batteries are present in a variety of devices. The act of recharging them generally involves a charger wired to a wall outlet being plugged into the device. The charger can determine the type of charge the batteries receive and therefore determine the cycle life of the batteries. Wireless power transfer is on the cutting edge of the battery charging world. There are el...

Simultaneous Wireless Power/Data Transfer for Electric Vehicle Charging

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...

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...
