Wireless Power Transmission: An Innovative Idea
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 . .

TELKOMNIKA Telecommunication Computing Electronics and Control, 2018
Wireless electrical energy transfer has many advantages over the same through conducting cables. This research focusses on developing wireless power transfer circuit using inductive coupling. The experiment has been done by changing the numb er of turns and the diameter of the wire of a coil with the aim of finding the maximum power and the longest distance that the energy can be transferred through wireless means. The power source is connected to a series of electronics components and a copper coil which form the primary source for the transmitter the power receiver consists of a copper coil, a rectifier and the load. In a system with the diameter of the wires of the two coils is0.5 mm, and the number of turns is 26 at the frequency of 470KHz the efficiency of power transfer about 1.51% at a distance of 1 cm. The transferred energy by wireless means could operate a 1 Watt LED at 1 cm.
—Wireless Power Transmission through inductive coupling is one of the new emerging technologies that will bring tremendous change in human life. Due to shortage of time and fast running life style it is difficult to carry the complete charging set which increases the demand of the wirelessly charged products. Wireless power transfer is one of the simplest and inexpensive ways of charging as it eliminate the use of conventional copper cables and current carrying wires. In this paper, a technique is devised for a wireless power transfer through induction, and a feasible design is modeled accordingly. The technique used in this paper is the inductive coupling as it the easiest method of high efficiency power transfer without using wired medium (eg, transformer). In this paper the result of experiment is given which is done to check wireless working of a simple application by glowing LED, and charging a mobile. Wireless power transfer is not much affected by placing hurdles likes books, hands and plastic between transceiver and receiver. This research work focuses on the study of wireless power transfer for the purpose of transferring cut and dried amount of energy at maximum efficiency.

The concept of transferring electrical power to a load wirelessly is an intimidating and a challenging idea. The genius of powering systems wirelessly has pulled the curtains to a new world. In the 19 th century, Nikola developed 'Tesla Tower' in hope to transfer power wirelessly. Since then, the world is trying hard to say goodbye to wires. WPT using Inductive Coupling which falls under the domain of NFWPT, uses a transmitter coil to transmit power 109
Wireless Power Transmission Using Resonance Inductive Coupling
In this paper, we present the concept of transmitting power without using wires i.e.transmitting power as Magnetic waves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Resonance Inductive Coupling (RIC). We also discussed the technological developments in Wireless Power Transmission (WPT). The advantages, disadvantages, biological impacts and applications of WPT are also presented. Wireless power or wireless energy transmission is the transmission of electrical energy from a power source to an electrical load without man-made conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous, or impossible. the proportion of energy received becomes critical only if it is too low for the signal to be distinguished from the background noise. With wireless power, efficiency is the more significant parameter. A large part of the energy sent out by the generating plant must arrive at the receiver or receivers to make the system economical.The most common form of wireless power transmission is carried out using direct induction followed by resonant magnetic induction. Other methods under consideration are electromagnetic radiation in the form of microwaves or lasers and electrical conduction through natural media
Study of wireless power transfer by Induction Technique
Electricity is the basic need of our world now a day. We are using wires for the transmission of the electrical power. And we are also facing a lot of problem due to the wires. Today we are bound to compromise with those problems because we are not having any other technology to transmission of power. Scientists and engineers are working to eliminate this problem by isolating the wires from the transmission lines. This technology is named as wireless power transfer system. According to near and far field there are some classifications of the wireless power transfer. Induction is the one of the near field or non radiative technique of the wireless power transfer system. In this paper we have explained the brief idea about this technique. In this technique there will be the conversion of energy from electrical to magnetic energy in the transmitter and then transmitted. Again in the receiver the magnetic energy is converted in the electrical energy and supplied to the load. In this paper we have explained the method of the conversion of energy on both transmitter and receiver side. Also the function of the generated magnetic field is explained. Some practical results of our device are also explained in this paper.

2017
Access to power is a fundamental requirement for the effective functioning of any electrical/electronic circuit. The conduit of transfer of power can be either physical (wires, cables etc.) of non-physical (i.e. wireless). Wireless power transfer is a broad term used to describe any means used to transmit power to electricity dependent systems and devices. In this paper, a wireless power transfer system is developed to provide an alternative to using power cords for electrical/electronic devices. With this technology, challenges like damaged or tangled power cords, sparking hazards and the extensive use of plastic and copper used in cord production are resolved and also the need for batteries in non-mobile devices is eliminated. In this system, electromagnetic energy is transmitted from a power source (transmitter) to an electrical load (receiver) via resonant inductive coupling. The performance achieved is a good indication that power can still be transmitted over a medium range. I...
