摘　　要：针对双向无线电能传输系统的控制策略较复杂,需要综合考虑能量流动大小和流动方向的问题,采用二端口网络理论对基于双边LCC补偿网络的双向无线电能传输系统进行数学建模,得到系统有功功率和无功功率的传输特性,进而提出采用有功功率大小与极性分别控制能量流动大小与方向的控制策略,通过Matlab/Simulink软件进行仿真验证。所提控制策略无需切换模式,便可实现能量的双向流动,且保证较高的传输效率,为无线电能传输技术应用于车网互联系统中提供有益指导。The control strategy for the bidirectional wireless power transfer(BWPT)system is complex and requires careful consideration of the size and direction of energy flow.The two-port network theory is used to establish a mathematical model of the BWPT system based on LCC-LCC compensation network,to obtain the active and reactive power transmission characteristics,and then propose a control strategy that uses the active power size and polarity to control the size and direction of the energy flow respectively.The simulation verification is carried out using Matlab/Simulink software.The proposed control strategy can achieve bidirectional energy flow without switching modes and ensure high transmission efficiency,providing a useful guide for the application of wireless power transfer technology in the vehicle to grid system.
