摘要
基于谐振原理,对带有复合谐振网络的电场耦合式无线电能传输(CCPT)系统进行了研究。利用LCL网络实现发射端恒流,利用CL网络实现负载恒压,提高了系统的稳定性。整个系统结构简单,无需复杂的控制电路即可实现稳定输出,特别适合于耦合电容和负载经常变化的恒压输出场合。通过分析网络电路模型,推导出了耦合电容电流和负载端电压的计算公式,并进一步得到了各元件参数设计公式。最后通过仿真和实验,验证了分析方法的正确性和设计的有效性。
Based on the principle of resonance, a capacitively coupled wireless power transfer（CCPT） system with composite resonant network is investigated.LCL network is applied to realize the constant current in transmitting terminal and CL network is applied to realize the constant load voltage which can improve the stability of the system.The CCPT system has simple structure and stable output without complex control circuit which is particularly suitable for constant voltage output occasions in the context of the coupled capacitor and load frequently changing.Through the analysis of network circuit model, the expressions for coupled capacitor current and load voltage are obtained, and then each component parameters formulas are deduced.The correctness of the analysis and effectiveness of the design are verified by simulation and experimental results .
