摘　　要：为了进一步研究谐振式无线电能传输(Resonant Wireless Power Transfer)技术,根据WPT技术的传输原理,提出了一种基于串—串(SS)型结构的无线电能传输模式。基于串联谐振和并联谐振等效电路的计算比较,结合WPT的SS、SP、PS、PP四种拓扑结构和补偿电容的计算公式,确定系统发射端选用串联谐振电路最合适。为了便于分析和计算,本研究选定串—串(SS)型系统进行研究。进一步根据基尔霍夫定律,建立系统负载功率和系统能量利用率的模型,进而提出提高电能利用率的措施。利用PSpice软件绘制电路图并仿真验证,得到实验结果与理论分析结果一致,为下一步的研究提供了有效的基础。In order to further study the Resonant Wireless Power Transfer technology,a wireless charging mode based on the series-series（ SS） structure was proposed according to the transfer principle of WPT technology.Based on the correlation analysis of series resonance and parallel resonant equivalent circuit as well as combined with four topologies of SS,SP,PS,PP and the calculation formula of compensation capacitance,the series resonant circuit was verified as the fittest one for the system transmitter. In order to facilitate the analysis and calculation,the series-series（ SS） structure was selected for the research. Furthermore,according to the Kirchhoff＇s law,a model of system load power and energy utilization was established,and measures for improving the power utilization rate were proposed.And the PSpice software was employed to draw the circuit diagram,and the following simulation verification was carried out,then it is found that the experimental results are consistent with the theoretical analysis ones,which provides an effective basis for the next research.
