 Abstract
In this paper, using the globular structure designed and implemented for the transmitter and the receiver resonant wireless power transfer(WPT). The coil of the transmitter was proposed to emit a magnetic energy in three-dimensional space by winding a ball shape. Each side of the transmitter has been designed to obtain a high Q value by a spiral structure. This solves the problem that the transfer efficiency decreases rapidly depending on the location in the conventional WPT. The resonance frequency is used 6.78 MHz and the distance between the trasnitter and the receiver is 200 mm. The transfer efficiency of the proposed WPT system is higher than 40% at all direction.
