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.
Future with wireless power transfer technology
Journal of Electrical & Electronic Systems, 2018
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
Design And Construction Of Wireless Charging System Using Inductive Coupling
Wireless charging system described by using the method of inductive coupling. In this project, oscillation circuit converts DC energy to AC energy(transmitter coil) to transmit magnetic field by passing frequency and then induce the receiver coil. The properties of Induction coupling are wave(magnetic field-wideband), range(very short~cm), efficiency(hight) and operation frequency(LF-band~several handred kHz).The project shows as a small charging for 5V battery of phone in this method. The system bases on coupling magnetic field, then designed and constructed as two parts. There are transmitter part and receiver part. The transmitter coil (transmitter part) transmits coupling magnetic field to receiver coil (receiver part) by passing frequency at about 1.67MHz. The Ampere's law, Biot-Savart law and Faraday law are used to calculate the inductive coupling between the transmitter coil and the receiver coil. The calculation of this law shows how many power transfer in receiver part when how many distance between the transmitter coil and the receiver coil. The system is safe for users and neighbouring electronic devices. To get more accurate wireless charging system, it needs to change the design of the following keywords.
Wireless Power Transmission by Inductive Coupling
Journal of Control and Instrumentation Engineering, 2019
In this paper we have explain how WIRELESS POWER can be transmit form one place / one point to another place / other point. In this paper we have told what are the requirements of wireless power transmission, like advantages, how it works, why it works, the circuit diagram, the block diagram etc. Wireless power transmission is the one source in which power / electricity can be transmitted through wireless. It is one of the source in which power can be transmitted without any use of wire.
The Wireless Power Transmission(WPT) topic was investigated from the early 19 th century and still is, over numerous applications of Technology starting right from recharging the mobile devices up to transmitting power over short and long distance i.e. to transmit power to earth from high energy systems of satellites equipped with solar panels. The recharging of small mobile systems was pretty much achievable by means of Inductive coils whereas the WPT over the long range such as Solar Power Satellite (SPS) Technology is still under a question of accountability & affordability as it need to be practical, inexpensive & efficient over the long run.
