摘要

研究了不同电磁超材料(MTM)加载方式下磁耦合共振无线输电系统(MCR-WPT)传输特性。首先,设计了工作频率为6.78 MHz的原始MTM;其次,分析了MTM的磁场浓度和抗失调特性。最后,实验研究了不同加载方式和mtm数量下MCR-WPT系统的传输特性。研究结果表明,当传输距离为400 mm时,在发射线圈和接收线圈之间加载MTM时,加载1片、2片和3片MTM的MCR-WPT系统的最大传输效率分别为28.57%、42.27%和41.5%。当MTM距离传输系统30 mm时,四面环绕式MCR-WPT系统的传输效率为38.72%,比双面MCR-WPT系统的传输效率提高6%。当传输距离在200 ~ 500 mm范围内变化时,通过调整mtm的加载方式可以使MCR-WPT系统的传输效率最大化。研究结果可为进一步提高中长距离MCR-WPT系统的传输效率提供参考。

Transmission characteristic analysis of magnetic coupling resonance wireless power transfer system with different loading methods of electromagnetic metamaterials

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.
