摘要
基于磁场耦合理论提出磁耦合谐振式无线电能传输技术方案,建立发射端电路和接收端电路以及整体电路的模型。首先,建立磁场耦合谐振式无线电能传输系统模型和等效电路。其次,设计发射端电路与接收端电路,并对电路参数进行配置。然后设计系统整体电路,计算接收端电路输出功率及电能传输效率。最后,利用电路仿真软件对系统进行仿真,得到系统性能参数,并分析系统的可行性。仿真结果表明,系统的传输效率随工作频率的增大而降低,但输出功率有所下降,传输效率为68.04%时,输出功率为4.26W。
Based on the theory of magnetic field coupling,a magnetic coupling resonant radio energy transmission technology scheme is proposed,and models of the transmitting end circuit,receiving end circuit,and overall circuit are established.Firstly,it establishes a magnetic field coupled resonant wireless energy transmission system model and equivalent circuit;secondly,designs the transmitting and receiving circuits,and configures the circuit parameters;then designs the overall circuit of the system,calculates the output power of the receiving circuit and the efficiency of electrical energy transmission;finally,it uses circuit simulation software to simulate the system and obtain system performance parameters,and analyzes the feasibility of the system.The simulation results show that the transmission efficiency of the system decreases with the increase of operating frequency,but the output power decreases.When the transmission efficiency is 68.04%,the output power is 4.26W.
