The main objective of this project is to develop a device for wireless power transfer. The concept of wireless power transfer was realized by Nikolas tesla. Wireless power transfer can make a remarkable change in the field of the electrical engineering which eliminates the use conventional copper cables and current carrying wires.

Based on this concept, the project is developed to transfer power within a small range. This project can be used for charging batteries those are physically not possible to be connected electrically such as pace makers (An electronic device that works in place of a defective heart valve) implanted in the body that runs on a battery.

The patient is required to be operated every year to replace the battery. This project is designed to charge a rechargeable battery wirelessly for the purpose. Since charging of the battery is not possible to be demonstrated, we are providing a DC fan that runs through wireless power.

This project is built upon using an electronic circuit which converts AC 230V 50Hz to AC 12V, High frequency. The output is fed to a tuned coil forming as primary of an air core transformer. The secondary coil develops a voltage of HF 12volt.

Thus the  transfer of power is done by the primary(transmitter) to the secondary that is separated with a considerable distance(say 3cm). Therefore the transfer could be seen as the primary transmits and the secondary receives the power to run load.

Moreover this technique can be used in number of applications, like to charge a mobile phone, iPod, laptop battery, propeller clock wirelessly. And also this kind of charging provides a far lower risk of electrical shock as it would be galvanically isolated.

This concept is an Emerging Technology, and in future the distance of power transfer can be enhanced as the research across the world is still going on.

I came across Edgefx while I was searching for wireless based projects in the Google.I had 3 reasons to purchase kit from Edgefx.Site looked quite comfortable.COD available.
Prices are worth.Its taken a while for delivery but yes I received all the right components along with the kit. I would like to suggest you to increase the size of the choke in the kit.

The kit delivered on time with the right components.I satisfied with the technical support provided by Edgefx. Initially I confused by seeing coding commands afterwards I understood.I will recommend Edgefx to all in future.
