资料介绍

阐述了磁耦合谐振式无线电能传输的工作原理,在对发射与接收电路几种拓扑结构分析的基础上设计了一个收发电路均采用串联补偿结构、谐振频率为lMHz、负载为10Ω的模型。基于线圈的互感耦合等效模型,从电路角度分析得出系统的输出功率和效率与线圈、负载、互感等参数之间的关系。针对磁耦合谐振系统满足最大输出功率时效率比较低的状况,提出了功效积指标。在满足系统输出功率的基础上,该指标实现了较高的传输效率。最后,通过Matlab仿真验证了所提功效积指标的可行性.

Firstly, this paper expounds the principle of magnetic coupling resonant wireless power transfer. Based on the analysis of the transmitting and receiving circuit topologies, a model is designed with a resonance frequency of 1 MHz and a load of 10 12. The transmitting and receiving circuit of the model are used in series compensation structure. In this paper, the relationship among output power, efficiency, coils, load, and mutual inductance are analyzed from the circuit point based on the coupling mode of two coils. According to the condition that the magnetic resonance system satisfies the maximum power output with a low efficiency, this paper presents a power efficiency index. The index is a synthetic performance ...
