Abstract

Several customers want to charge their schemes such as mobile or wearable schemes wirelessly. Wireless power transfer technology using resonant magnetic coupling creates it probable to charge a receiver is distance between the transmitters. Conversely, the receiver can take different orientations over that distance, and this causes problems, such as great shrinkage in power transfer efficiency in certain cases. To solve this problem, we develop a method to control the magnetic field direction of the receiver. The objective of this manuscript is to design a wireless power transfer to charge their smart phones by using resonant magnetic coupling and also increase the efficiency by controlling the direction of the magnetic field corresponding to the different orientations of the receiver.
