Wireless power transfer (WPT) technology provides the best scheme for powering electrical equipment in a safe, flexible and clean way. Solving these issues, such as, signal transmission, online load identification, is the key to promote development of magnetically-coupled resonant WPT technology. According to the usage of harmonics in electric power system, this project proposes a novel magnetically-coupled resonant WPT system based on separation and multiplexing of harmonics, establishes a model of magnetically-coupled resonant WPT system based on two path of fundamental and harmonic waves, and the working mechanism of two path power transfer, signal transmission and load identification is clarified. This project explores a new idea to deal with these existing problems of magnetically-coupled resonant WPT systems, aiming at solving these key problems, such as effective separation of fundamental and harmonic waves, distribution and control of power in two path, physics and mathematics models of magnetic mechanism with four coils, and robustness of systems. This project will raise the level of basic theory of WPT technology. These research achievements would enrich WPT technology theory systems and make contributions to establishing basic theory of WPT technology, promotion and industrialization of WPT technology.
