Wireless power transmission (WPT) technology has been regarded as the best solution to the problems of wire power transmission since its concept is described by Tesla. In recent years, with the application of a large number of electrical equipment, the drawbacks of wire power supply has become more prominent. WPT has received wider attention and more development opportunities. As a core part of WPT system, the magnetic coupling mechanism (MCM) is the focus of most of the research. This article reviews and analyzes the design and optimization of MCM of WPT system. It mainly focuses on the forms of MCM designed to meet different power supply requirements, the optimization methods of MCM to improve the performance, and the electromagnetic safety of MCM to ensure the promotion and application of WPT system. For WPT system, the forms of MCM is the basis of WPT, the optimization of MCM is the guarantee of the system performance, and the electromagnetic safety of MCM is the premise of the applications. The review and analysis of this article covers the three cores of MCM. It can provide a reference for research groups, professionals, and investment representatives on WPT.
