Abstract In recent years, the research of wireless power transfer technology have been paid more attention by more and more electrical technology researchers while its application field have been continuously expanded. The coupling mechanism is an important part of the wireless power transfer, and its design and optimization have a direct influence on the transmission efficiency, transmission distance, power and misalignment tolerant of the system. In order to design the coupled magnetic mechanism, the current research status and hot issues from the three aspects of transmission coil, compensation network and electromagnetic shielding structure is briefly overviewed in this paper, and then the problems to be solved and the development tendency in the future are discussed, which providing a useful reference for other researchers.
