摘要
近些年人们对磁耦合谐振式无线充电电能传输的研究相当火热,传统的电路拓扑结构的研究已经相当地完善,本文基于较为新颖的LCC-P电路拓扑结构展开研究,依据电路相关理论推导出了系统传输效率的表达式。通过ANSYS Maxwell仿真软件,建立了线圈模型,分析了线圈参数,再将模型导入ANSYS Simplorer仿真软件,对磁耦合谐振式无线电能传输系统进行联合仿真。结果表明:电能传输效率随着负载的增大而减小;随着发射端串联谐振电感的增大而增大,且变化趋势较明显。仿真实验验证了理论的正确性。
In recent years,the research on the magnetic coupling resonance type wireless charging power transmission has been quite hot,and the research on the traditional circuit topology has been quite perfect.Based on the relatively novel LCC-P circuit topology,this paper studies the transmission efficiency of the system based on the circuit theory.The coil model was established by ANSYS Maxwell simulation software,the coil parameters were analyzed,and then the model was imported into ANSYS Simplorer simulation software for joint simulation of the magnetic coupling resonance radio energy transmission system.The results show that the power transmission efficiency decreases with the increase of load.The series resonant inductance increases with the increase of the transmitter,and the change trend is obvious.Simulation experiments verify the correctness of the theory.
