The concept of transferring electrical power to a load wirelessly is an intimidating and a challenging idea. The genius of powering systems wirelessly has pulled the curtains to a new world. In the 19th century, Nikola developed ‘Tesla Tower’ in hope to transfer power wirelessly. Since then, the world is trying hard to say goodbye to wires. WPT using Inductive Coupling which falls under the domain of NFWPT, uses a transmitter coil to transmit power to the receiver coil via a magnetic field. Inductive coupling is an efficient way to transmit power through short distances and making its way in smartphones and the health industry. Electric vehicle charging stations are also trending thanks to wireless power transfer. This paper discusses the theoretical foundation of Inductive coupling and presents results of an experimental work done on WPT via Inductive Coupling. In the process above, an efficiency of 72% was achieved.
