Abstract

This paper deals with wireless power transmission technology. A battery of an electronic device will be charged wirelessly. The solar panel converts the sun light into electrical energy. Power from a solar panel is sent through a transmitter circuit and received by a receiver circuit wirelessly based on Faraday’s law of induction. As magnetic resonance coupling is more efficient and useful than magnetic inductive coupling, in this paper, magnetic resonant coupling is used. There are a transmitter and receiver coil. The transmitter coil is driven at the same frequency of the resonant frequency of the receiver coil. For those reasons, the LC tuned circuit has been built to maintain the same frequency. As power is transmitted wirelessly, some power is wasted. As a result, efficiency is decreased to only 11 %. After all, it will be a future charging solution in the modern world. With the help of wireless battery charger technology, power can be supplied to the electric cars, drones, hospital’s equipment, and smartphones. This device also helps to reduce the necessity of using wires.
