The main function of WPT is to allow electrical devices to be continuously charged and lose the constrain of power cord . The main concept of WPT is to transfer electrical power from a source a device without the aid of wires. The technology behind wireless charging have been around for a long time the idea was initially suggested by Nikola Tesla, who demonstrated the principle of wireless charging it is already a reality in such devices as electric toothbrushes and surgically implanted devices, like artificial hearts.
Wireless charging, also known as inductive charging, is based on a few simple principles. The technology requires two coils: a transmitter and a receiver. An alternating current is passed through the
