摘要
针对磁短路整形对载流线圈空间磁场分布特性的影响以及对磁耦合无线能量系统传输距离、功率、效率的改变问题,采用解析法和磁场仿真分析法研究磁场短路整形所引起的线圈间耦合磁场的变化,并通过试验验证了采用磁短路整形模式可以在磁耦合式无线能量传输过程中提高系统的传输距离和功率,但同时降低了效率。研究证实了磁短路整形方式可以改进无线能量传输的性能。
Wireless power transfer via magnetic shorting shaping affects the magnetic field. The space magnetic field changes due to magnetic shaping between coupling coils were analyzed using calculation and simulation methods. Experimental results show that the magnetic shorting shaping mode increases the transmission distance and power in a magnetically coupled wireless energy transfer process, but reduces the efficiency. Overall, the magnetic shorting shaping can improve the wireless energy transmission performance with certain practical value.
