摘要:
针对电场耦合式无线电能传输系统( electricfield coupled power transfer, ECPT) 中归一化频 率的变化是否会对系统的最大输出功率和系统电能传输效率产生影响的问题,利用阻抗变换理论 对 CLC-S 谐振型电能传输系统进行建模分析,给出系统传输功率和效率的计算方法,并得出两个 结论:1) 随着归一化频率的变化,负载接收的最大功率点和系统最大传输效率点存在不一致性;2) 负载接收的最大功率在归一化频率略小于1 处取得。基于电路仿真的结果验证了以上理论分析结 论。最后,根据仿真模型设计了电场耦合式无线电能传输实验系统,通过实验结果进一步证明了理 论分析的正确性。?
Abstract:
?In order to confirm whether the frequency offset will influence the maximum output-power or efficiency of load in electricfield coupled power transfer ( ECPT) system, the circuit model of the ECPT system was studied with the help of the impedance transformation principle. The calculation method to transfer power and its efficiency was proposed. And there are two results through theoretical analysis. One is the inconsistency on maximum output-power and efficiency with the frequency offset and the other is the maximum power is obtained when the normal frequency is slightly less than 1. In the end,experiment device was designed and experimental results were well consistent with the theoretical analysis, which shows correctness of the proposed method and its result.
