摘要针对磁谐振式无线电能传输系统进行设计,需要在不同场合下挖掘其最优化传输性能。通过对磁谐振式无线电能传输系统特别是目前常用的含中继谐振器的四线圈无线电能传输系统进行相应的理论建模分析,采用参数归一化解析理论,探讨最优化传输效率及最大化输出功率的影响因素以及在设计过程中两种实现目标的内在关系。通过理论仿真及实验验证的方式得出在系统工作频率确定的前提下,磁谐振式无线电能传输系统最优化传输效率以及最大化输出功率一定不拟合。将理论结果应用到无线电能传输系统的设计中,发现在系统设计条件不变的前提下,存在确定匝数及半径的能量接收线圈可使得系统传输效率或输出功率达到最优化。

Abstract：When designing a magnetic coupling resonant wireless power transmission system,we need to seek optimal transmission performance under different situations.By modeling analysis for the magnetic coupling resonant wireless power transmission system,especially the four-coil-system with dual relays, we use normalized parameter analytical theory to explore the way of realizing optimal transmission efficiency and output power,as well as the internal relations between these two targets.By theoretical simulations and experiments,the optimal transmission efficiency and the optimal output power are not matching when the system operating frequency is determined.Ultimately,applying the theory results to the design of actual system,it is found that there are determined turns or radius of receiving coils which can provide maximum transmission efficiency or output power when other parameters of the system is unchanged.

Key words： Wireless power transmission magnetic coupling resonant transmission performance parameters normalized optimization
