| 磁耦合谐振式无线电能传输技术作为一种实现非接触电能传输的新技术，由于其相对于松耦合感应技术具有高传输功率和远传输距离等优势，成为了目前电气工程领域的一大研究热点。针对电动汽车和轨道交通车辆等大功率对象动态无线充电的应用趋势，根据准静态下的麦克斯韦数学方程，利用有限元电磁仿真软件，建立了多发射线圈阵列式磁耦合谐振式无线电能传输系统的三维仿真模型，通过实验测试验证了仿真模型的可靠性。在此基础上，通过有限元分析的方法研究了准静态下不同系统结构时接收端负载电压的稳定性及系统的电磁场分布特征，为电动汽车和轨道交通车辆动态无线充电系统结构的设计提供一定的理论参考。 |

| As a new technology to realize contactless electric energy transmission, wireless power transfer based on magnetic coupling resonant method has been one of the hottest topics in the field of electrical engineering at present, which is owing to high transmission power and long transmission distance in comparison with the loose coupling sensing technology. In light of the dynamic wireless charging forhigh power equipment, such as electric vehicles and rail transit trains, a three-dimensional simulation model of magnetic coupling resonant wireless power transmission with an array of transmitters is established using finite element electromagnetic simulation software and based on the Maxwell equation in quasi-static condition. The reliability of the simulation model was verified by experimental tests. On this basis, the stability of load voltage at the receiving terminal and the characteristics of electromagnetic distribution in a quasi-static condition and with different system structures were studied through finite-element analysis. The research result in this paper provides certain theoretical reference for the structural design of the dynamic wireless charging system for electric vehicles and rail transit trains. |
