Power wireless transferbased on a royeroscillator

Abstract

Wireless is not only for communication, but also for power transfer. This paper presented wireless power transfer prototype by using a Royer oscillator. From the experiment, it is obtained that At the transmitter, transmitted power increases exponentially to number of capacitors, so does the frequency. At the receiver, received power and frequency increase if number of capacitor in transmitted added. Maximum received power is 0.444 W and efficiency 96.5% at distance 7 cm.
