摘要：
随着无线电能传输技术快速发展,磁耦合式无线充电技术被广泛应用在锂电池充电领域.为进一步提升无线充电系统的安全性与充电效率,在串联串联(series-series,S-S)型补偿网络的基础上设计一种基于接收侧π/T型变结构补偿网络的恒流恒压无线充电系统.利用等效电路分别建立恒流和恒压充电的模型,通过附加的电容电感和开关改变接收侧拓扑结构,实现无线充电系统输出稳定的电流电压.该结构无需原边和副边复杂的控制和通信,几乎没有无功功率输出.通过DSP控制器作为恒流恒压输出的切换控制器.最后通过仿真和实验验证了基于接收侧π/T型变结构补偿网络恒流恒压输出特性和参数设计的准确性.
With the rapid development of radio energy transmission technology,magnetic coupling wireless charging technology is widely used in the field of lithium battery charging.In order to further improve the security and charging efficiency of the wireless charging system,this paper designs a constant current and constant voltage wireless charging system based on the π/T variable structure compensation network on the receiving side on the basis of the series-series(S-S)compensation network.The models of constant current and constant voltage charging are established respectively by using equivalent circuits.The topology of the receiving side is changed by adding capacitors,inductors and switches to achieve stable current and voltage output of the wireless charging system.The structure does not need complicated control and communication between the primary side and secondary side with almost no reactive power output.DSP controller is used as the switching controller of constant current and constant voltage output.Finally,the accuracy of constant current and constant voltage output characteristics and parameter design of π/T variable structure compensation network based on the receiving side is verified by simulation.
