Wireless Power Transmission of Laptop Charger

Abstract

We cannot imagine the world without electric power. Generally the power is
transmitted through wires. This paper describes an original idea to eradicate
the hazardous usage of electrical wires which involve lot of confusion in
particularly organizing them. Imagine a future in which wireless power
transfer is feasible: cell phones, household robots, mp3 players, laptop
computers and other portable electronics capable of charging themselves
without ever being plugged in, freeing us from that final, ubiquitous power
wire. Some of these devices might not even need their bulky batteries to
operate. This paper includes the techniques of transmitting power without
using wires with an efficiency of about 95% with non-radiative methods. Due
to which it does not effect the environment surrounding. These techniques
Includes resonating inductive coupling in sustainable moderate range. The
coupling consists of an inductor along with a capacitor with its own resonating
frequency. In any system of coupled resonators there often exists a so-called
“strongly coupled” regime of operation. If one ensures to operate in that
regime in a given system, the energy transfer can be very efficient. Another
technique includes transfer of power through microwaves using rectennas.
This is particularly suitable for long range distances ranging kilometers. With
this we can avoid the confusion and danger of having long, hazardous and
tangled wiring. This paper as a whole gives an effective, high performance
techniques which can efficiently transmit the power to the required area
varying in distances . .
