The main concept of this project is to transfer the AC power wirelessly from a power source to electrical loads using a high-frequency resonating air core transformer to develop the frequency from 50Hz to 40KHz for transferring power over a distance of 3cm.

 Wireless power transfer can make a remarkable change in the field of electrical engineering , which eliminates the usage of conventional copper cables and current carrying wires. Based on this concept, the project is developed to transfer the power within a small range.

This project can be used for charging batteries that physically are not possible to be connected electrically such as pace makers (An electronic device that works in place of a defective heart valve) implanted in human 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 that 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 from the primary (transmitter) to the secondary, which is separated with a considerable distance (say 3cm). Therefore, the transfer could be seen as the primary transmission and the secondary receives the power to run the load.

Moreover, this technique can be used in number of applications: to charge a mobile phone, iPod, laptop battery, and 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 got to know about edgefx through google. I was searching electronic related projects through that i got to know about edgefx website.
I have decided to buy project from edgefx because i need a kit which is fully assembled. So, that is why i have purchased project from edgefx. I like most about edgefx is fully assembled kit.
the support team has helped me in purchasing the project.
i would like to give reference to my friends and juniors.
