Abstract:
Nowadays wired chargers are used to power electronic devices such as Mobile phones, laptops, Electric vehicles and other electronics devices. A cell phone is a device which connects people around the world and they can communicate with each other while millions of miles away from one another which makes a cell phone a very important electronic device. Time is money and one does not simply want to put mobile on charging and put work on hold. Charging the phone and giving time on that is a big problem. Due to the limitations of wired charging like power losses, risk of short circuit, inconvenient etc, the battery powered devices are facing technical problems. Keeping these problems in mind, our project team came up with innovative idea of charging phone wirelessly. Wireless power transfer (WPT) holds the promise of freeing us from these limitations, using this technology electronics devices can be powered wirelessly. Inductive power transfer (IPT) technique is used in charging pads developed by different companies like apple, Samsung etc. which although charges the device wirelessly, but the pads are not portable due to the restriction of alignment along with very short range usually in millimeters which makes them less efficient. The basic aim of this project is to propose the use of a simple, cheap and easiest technique for charging cell phones. Inductively coupled wireless power transfer is a new technology to transfer electrical power wirelessly between the source and load. It is a technique that we will be using to improve the range and efficiency of Wireless chargers and facilitate in adapting WPT as a permanent solution to wired charging. In comparison of IPT with Inductively Coupled-WPT the range will increase from few millimeters to inches as well as the efficiency increases notably.
