Abstract

Process of transferring electricity between two points is referred to as Wireless Power Transfer (WPT). One of the problems to implement WPT is a distance. Most of the system needs to put the transmitter and receiver closely. This paper discusses the transmission power using the resonant frequency method. 100Watt of power transmission had been designed to transmit electrical energy. The method was used to analyze the different size of the coil. The coil with diameter size 160cm had been tested with open area, embed to the earth’s surface and coil size 16cm as a reference. The purposed of design to identify the performance of coil transmission in WPT system. To get the larger area cover for WPT system, the larger size of the coil had been developed. In the experimental transmission with a larger size is in demand in many applications. Increasing the size of the coil can increase the distance approximately to 10 times. The power transfer also shows less than 1% of power losses when embedding into the soil.
