Abstract — In this paper, we study the performance of wireless power transfer with various receiver positions being at 00, 900, and 1800 with a developed transmitter/receiver and 2 structure magnetic resonant coils. Both of the Transmitter and Receiver couplings are made of enamel coil. Based on experimental performance of wireless power transfer with various receiver positions by using magnetic resonant coil no effect was significant when tilted at 00, 900, and 1800. Keywords - Tilted; power transfer; magnetic resonant coil..

INTRODUCTION

DC Source

Wireless power transfer (WPT) [1] or wireless energy transmission is the transmission of electrical power from a power source to a consuming device without using solid wires or conductors.[2,3,4,5] It is a generic term that refers to a number of different power transmission technologies that use time-varying electromagnetic fields. Basically, wireless charging technology similar to that used in the transformer (better known as Transformer) or dynamo powerhouse. Laws of physics, if an electrified wire coil magnetic field will arise. Conversely, if the coil is subjected to a magnetic field, then there will be electricity in a wire coil.
