摘要
针对无线电能传输(WPT)系统存在的抗偏移性差、耦合机构复杂的问题,在此提出了一种基于LCC-S补偿的双发射双接收(D-LCC-S)四通路WPT系统,可实现WPT系统的抗偏移恒压输出。首先对系统进行详细的理论分析,然后给出了电路参数和耦合机构的设计方案,最后搭建了一台150 W实验样机对理论分析进行验证。实验结果表明,系统传输效率可达88%,耦合机构发生水平横向和纵向偏移时,均可实现恒压输出,验证了系统设计的可行性和抗偏移特性。
Aiming at the problems of poor anti-misalignment and complexity of coupling mechanism in wireless power transmission(WPT) system,a double transmitting and double receiving four-channel WPT system based on LCC-S compensated(D-LCC-S) is proposed,which can realize the WPT system anti-misalignment constant voltage output.At first,the detailed theoretical analysis of the system is carried out,and then the design method of the circuit parameters and coupling mechanism is given.Finally,a 150 W experimental prototype is built to verify the theoretical analysis.The experimental results show that the transmission efficiency of the system can reach 88%,when the coupling mechanism is misalignment horizontally and vertically,the constant voltage output can also be achieved,which verifies the feasibility and anti-misalignment performance of the system design.
