Literature Review on Wireless Power Transmission by Magnetic Resonance Coupling Method

Abstract

Today, the widespread use of mobile electronic devices has brought about the advancement of wireless charging technology. Easy charging of these devices with wireless power transfer provides a wide area for users in terms of usability. Energy transmission efficiency is one of the most important parameters in wireless power transmission, which has become one of the popular fields of study recently. Especially in recent years, many studies have been carried out with different techniques on this subject, which brings advantages such as freedom of movement and ease of use by eliminating the problems caused by the cable. A review study on the magnetic resonance coupling method, which enables wireless power transmission with high efficiency at medium distance, is presented. It is aimed that this article will serve as a guide for researchers who will study on wireless power transmission and readers who are interested in this subject, where they can easily access related studies. In our study, firstly, the history of wireless power transfer is given, and then the issues that highlight the magnetic resonance coupling method, one of the wireless power transfer techniques, are included. Then, the basic principle of magnetic resonance coupling method is explained; maximum power transfer, maximum efficiency, alignment problem and its effects on human health are mentioned. Finally, electric vehicles and consumer electronics, biomedical implants, unmanned aerial vehicles and robots, which are the most intense application areas in wireless power transmission, are classified and the studies in these areas are included.
