Abstract

In this paper, the author investigates the fundamental of wireless electricity. One of
the known way to transfer power wirelessly is through electromagnetic induction
between two coils. Electromagnetic induction is the process of inducing electrical
current in a closed loop in the presence of changing magnetic field. By introducing
resonant frequency to the changing magnetic field, it is believe that the distance
between the two coil to transfer power wirelessly can be increase. Modern world has
seen the uses of mobile electronic peripherals such as laptops and cellphones, it is
known that such peripherals run on battery and need to be recharged on routine basis.
The user usually find very inconvenient to charge their peripheral when there are
many power cables messing around the power socket. Thus, the objective of this
project is investigate the resonant inductive power coupling in wireless electricity.
The proposed methodolgy then used to develop a prototype of wireless cellphone
charger. Prior to prototype development, several design parameters is investigated in
determining optimum prototype design. From the result gained, it is proven that
resonant inductive power coupling method can transfer power wirelessly over short
distance. The prototype developed is proven to be able to charge the cellphone
battery. This project serves as the fundamental works on this topic thus further
studies need to be carry out so in the future, we might be able to enjoy the novel
wireless power distribution system .
