基于多谐振耦合的无线电能和信息同步传输技术研究

In many practical applications, we not only need the wireless power transfer, but also require the real-time unidirectional or bidirectional information synchronous transfer. According to the unity of magnetic resonance wireless power transfer theory and magnetic resonance communication theory, the project proposes an efficient solution with multi-band resonant coupling technology, and research on the key scientific issues, achieving mid-range wireless power and bidirectional information transfer using shared coupling mechanism. We propose a multi-band resonant coupling mechanism with high resonant capacity, and research the integrative modeling method based on circuit and magnetic theory, then propose an inverse optimum design method of systematic structural parameters based on the forward model and multi-objective optimization algorithm, which provides theoretical guidance for the establishment of the actual system. Aiming at the difficult problem of transferring power and information synchronously when load or the receiving end’s position changes dynamically, we research the adaptive hybrid control strategy based on the impedance matching and source frequency regulation, improving the efficiency and stability. In order to further expand the applied range, we research the power and bidirectional information transfer technique,and the relay enhancement technique. On the experimental study, we introduce the technology into AGV wireless power supply system to improve the convenience and flexibility. Innovative achievements of the project will promote the development of wireless power and information transfer, and enrich the theoretical and technical systems.
