Review of Magnetic Coupling Resonance Wireless Energy Transmission

Abstract

This paper reviews the magnetic coupling resonance wireless energy transmission from the principle, models and theories based on the development and classification of wireless energy transmission technologies. Firstly, it introduces MIT coupled mode theory and the main circuit theory models and experiments, summarizes and illustrates the characteristics of the two theories. Secondly, it introduces the worldwide research progress in this area, including the circuit theories, three-coil energy transfer systems, multi-receptor, four-coil energy transfer systems, frequency tunable resonance body, adaptive tuning and frequency division, the loss distribution, new materials, mutual inductance coupling and frequency tracking. Finally combined with the main research content of magnetically coupled resonant wireless energy transmission, it points out the existing problems and the direction for the studies of the theory and application next step.
