ABSTRACT
Wireless power transfer systems depend strongly on the ability to couple energy from a source to a receiver through the use of a combination of inductors and capacitors. Depending on how the inductors and capacitors are combined, the resulting outcomes may be termed loosely coupled wireless power transfer, strongly coupled WPT, microwave wireless power transfer, or capacitive power coupling. Depending on how the inductors and capacitors are combined, the resulting outcomes may be termed loosely coupled wireless power transfer, strongly coupled WPT, microwave wireless power transfer, or capacitive power coupling. Although the theory of resonant wireless power transfer is well established, there are fundamental details often clouded by the way and manner authors in current literature have addressed the problem. Two broad approaches have been used to explain resonant wireless power transfer. Indeed, this requirement is well understood from electric power generation theory.
