摘　　要：无线电能传输(WPT)被广泛用于飞机、电动汽车、手机等领域,磁耦合谐振技术(Magnetic Coupling Resonance,MCR)是实现WPT的技术手段之一,具有效率高、传输距离远等优势。针对传统MCR技术的单线圈传输系统输出功率有限的缺点,采用一种前级双线圈传输系统,前级利用两个线圈进行并联,同时进行双磁场耦合谐振式电能传输,共同给负载供电,以期输出功率放大。同时,采用模型预测控制方法对逆变器进行控制,利用模型预测控制的高抗扰性去优化WPT系统的稳定性。仿真和实验验证了所提系统的有效性。Wireless power transfer(WPT)is widely used in aircraft,electric vehicles,mobile phones and other fields.Magnetic coupling resonance(MCR)is one of the technical means to realize WPT,which has the advantages of high efficiency and long transmission dis-tance.In view of the limited output power of the single coil transmission system of traditional MCR technology,a double coil transmis-sion system is proposed,which uses two coils in parallel and carries out double magnetic field coupling resonant power transmission at the same time,so as to jointly supply power to the load in order to amplify the output power.At the same time,the model predictive con-trol method is used to control the inverter,and the high immunity of model predictive control is used to optimize the stability of WPT sys-tem.Simulation and experiments verify the effectiveness of the proposed system.
