Wireless Power Transfer by Using Inductive Coupling

Abstract

The Wireless power transfer (WPT) is an efficient transmission of transferring the power without using wires or electrical conductors as a physical connection. The Wireless power transfer can eliminate the use of the wires and the batteries, thus increasing the mobility, convenience, and safety of an electronic devices for all users. The objective of this paper is to design and construct a method to transmit power wirelessly through air gap and charge low power devices. Wireless power transfer is useful to power electrical devices where interconnecting wires are inconvenient, hazardous, or are not possible.
