As a mid-range WPT technology, magnetically-coupled resonant WPT (MCR-WPT) has become a research focus ever since the research findings were published by Massachusetts Institute of Technology in 2007. This paper mainly dealt with the new progress of MCR-WPT, on the foundation of the brief introduction of WPT technology. Firstly, the basic structures and principles of MCR-WPT were analysed and the leading theories for MCR-WPT were introduced. Then the transfer level and hot topics of MCR-WPT were categorized and elaborated, in terms of transfer characteristics, new materials, interference and practical
