摘要
为优化无线电能传输系统参数对传输效率的影响,获得最大传输效率,首先,分析无线电能传输系统的电路等效模型的频率响应,求解出系统传输效率与参数之间的关系,验证了过耦合条件下的频率分叉导致系统传输效率降低;其次,提出了一种基于自动控制获取最佳系统共振频率及线圈方向角的最大传输效率无线电能传输系统设计方法 .Multisim仿真结果表明,在过耦合情况下,本系统能够有效提高系统的传输效率,其传输效率可提高 43% 以上 .
The relationship between transmission efficiency and system parameters has been obtained by analyzing the frequency response of the transmission system equivalent circuit model,and the decrease of transmission efficiency caused by the frequency bifurcation phenomena in the over-coupling condition has been verified.The design of maximum-efficiency system to acquire the best resonant frequency and coil direction angle based on automatic control has been presented.The simulation based on Multisim12 soft-ware showed that the transmission efficiency can be improved in the over-coupling condition and it can reach 43%.
