Abstract
In this paper, a wireless power transmission system (WPT) using the method of inductive coupling with the use of magnetic resonance technique to charge portable devices within a small distance of several centimeters is discussed and presented with full overall illustration on the methodology and results of the project. This technology of the WPT is built to eliminate the use of wires in our everyday life, tackling the constraints of wired charging technology such as lack of universal electrical standard, untidiness and unreliability for more convenient modern lifestyle. The system in this project main power supply is the normal wall power outlet (AC 230-240V 50/60Hz), and the system includes a power adapter, oscillator, transmitting coil and receiving coil and rectifier as main components of the system which all will be discussed in this paper. The prototype of this project was simulated before implementation in the hardware using protues8 software. The resonant magnetic coupling frequency which the system works on is 800 kHz ± 20 kHz with a maximum distance of operation of 4 cm transmitting about 1.5V. The objective of the project was all done successfully with in a limited time frame. The significance of the project can help to eradicate the use and need for wires in the future. Moreover, the future studies and researches that could be done in light of this one, includes the study of the system efficiency, oscillator circuit, coil design, and a WPT system with multiple loads.
