Transmission characteristic analysis of magnetic coupling resonance wireless power transfer system with different loading methods of electromagnetic metamaterials
The transmission characteristics of the magnetic coupling resonance wireless power transfer (MCR-WPT) system with different loading methods of electromagnetic metamaterials (MTM) are studied in this paper. Firstly, a primitive MTM with a working frequency of 6.78 MHz is designed. Secondly, the magnetic field concentration and anti-misalignment characteristics of the MTM are analyzed. Finally, the transmission characteristics of the MCR-WPT system with different loading styles and quantities of MTMs are researched experimentally. The research results show that when the transmission distance is 400 mm and the MTMs are loaded between the transmitting coil and the receiving coil, the maximum transmission efficiencies of the MCR-WPT system loaded with one, two, and three pieces of the MTM are 28.57%, 42.27%, and 41.5%, respectively. When the MTM is 30 mm away from the transmission system, the transmission efficiency of the four-sided surround type MCR-WPT system is 38.72%, which is 6% higher than that of the two-sided MCR-WPT system. When the transmission distance changes from 200 to 500 mm, the transmission efficiency of the MCR-WPT system can be maximized by adjusting the loading method of MTMs. The results can provide a reference for further improving the transmission efficiency of the middle- and long-distance MCR-WPT systems.
