摘　　要：在手机无线充电过程中,电池阻值的变化会导致输出电压或电流不恒定。针对此特性,结合磁耦合谐振式电能传输技术,提出一种基于移相控制方案的控制策略来维持系统的充电输出稳定。利用MATLAB中的相应模块对电路模型进行仿真搭建并对控制环节进行参数设计,在相应时间段研究阻值改变时的系统运行状态,维持其恒压、恒流的输出特性。In the process of wireless charging of mobile phones,the change of battery resistance will cause the output voltage or current to be inconstant.In view of this characteristic,combined with the magnetic coupling resonant power transmission technology,a control strategy based on the phase-shift control scheme is proposed to maintain the stability of the charging output of the system.Use the corresponding modules in MATLAB to simulate and build the circuit model and design the parameters of the control link,study the system operating state when the resistance value changes in the corresponding time period,and maintain its constant voltage and constant current output characteristics.
