2021

Wireless power transmission (WPT) is an effective method of transmitting electric power from one end to another through vacuum or atmosphere without using conventional wire or any other substance. The principle of inductive coupling is the key of transferring power for WPT. The power transfers from the transmitter section to the receiver section wirelessly through inductive coupling. Received power is amplified and rectified to supply in the load, which is a mobile phone in this project. <br>

An Overview of Wireless Power Transmission (WPT

International Journal of Information and Technology, 2016

it is imperative to note that in our daily life electricity is an essential factor as it contributes largely to the success of activities; this has led to a greater demand for electricity transmission which happens to be the most essential component of any control system. It also has its setback as there is always a fraction of loss during transmission and as such it is important to have an efficient transmission of power; this has given rise to the wireless power transfer system. Regardless of the technological concerns, wireless power transfer system in its capacity will expunge the use of wires or cables by providing individuals the option of recharging the dead batteries of devices effortlessly in the same manner as using a wireless communicator. A concise report and evaluation on the several methods of wireless power transmission is shown and discusses the advantages and disadvantages as well as the analysis and comparison of each method.

A Experiment Method of Wireless Power Transfer for Charging Devices

Wireless Power Transfer Technology would be applied in the charging devices. For example Electric Vehicles. Due to the global warming is very serious, the fossil fuels are dwindling. For this situation, it can use the battery to operate the cars, we are looking for some of the renewable energy. Therefore, the electric vehicles technology and skill are most popularity and mature. Many people have replaced to an electric vehicle, although the cost more expensive than the petrol vehicle, to reduce the use of fossil fuels are worth. Since the electric vehicle supporting is not much, especially for the electric vehicle chargers. Government and manufacture not enough information & details of the electric vehicle, it is difficult to see the charger facility which locates at the public area or parking, therefore cause inconvenient. This technology is taken widespread to use of an electric vehicle. For this project separate in two stages, the first stage to find out the relationship of frequency(f), capacitance(C) and inductance(L) by the much lab experiment and calculation. In stage two, develop a hardware model to deliver the wireless power transfer system can be recharged for mobile phone and model car wirelessly and find out the better combination and method through comparing a different kind of coil density and distance.

Design and Construction of a Prototype Wireless Power Transfer Device

2019

This project is aimed at developing a prototype wireless charging system that allows for charging convenience using wireless charging also called inductive charging. This allows charging to be made easier and free from connecting leads between charger and handset. In order to successfully achieve this task, the design of the prototype was developed in two parts, a transmitter with resonator and a receiver with resonator. The transmitter converts DC voltage to AC, and transfers energy wirelessly through an LC resonator to the receiver through mutual induction, and hence induces EMF in the receiver. The EMF is rectified, filtered and regulated and output is used to charge mobile phones. Testing results and measurements taken on this prototype shows that significant amount of EMF can be induced at receiver through air coupled transformers due to EM waves at high frequencies. The charging distance is 3cm maximum with end-to-end coupling.

Wireless power transmission is the way to transfer power without using wire. Wireless power transmission helps to connect those area where people are unable to get a suitable power source. Everyone can get clean and green wireless power. In future all the devices will relate to the power supply source wirelessly. In this paper we have presented the successful experimental attempts to transmit power wirelessly and future scope of wireless power transmission. We have tried to represent the future use of wireless power transmission in various areas where wired power transmission is impossible to supply implement.

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 . .

An efficient method for wireless power transfer would also enable advances in such diverse areas as embedded computing, mobile computing, sensor networks, and micro robotics. The need to minimize energy consumption is often the main design driver in applications where devices need to operate without tethered. Energy consumption often restricts functionality in such applications. The work depicted in this paper is inspired by potential application of magnetic resonant coupling as a means for WPT from a source coil to a single load Several experiments regarding this technique need to carry out for a better output and the day is not far when the need for wires will get obsolete
