摘要
通过耦合模理论推导出无线电能传输系统发射和接收线圈之间实现能量高效转移的条件,利用等效电路模型对磁耦合谐振线圈进行分析,通过MATLAB仿真软件,得出耦合谐振线圈各参数与传输效率的关系.通过对具体模型进行优化,模型效率明显提高,为耦合线圈的优化设计提供依据.
By the coupled mode theory, the conditions of efficient energy transfer between the wireless power transfer system for transmitting and receiving coils was derived, then the coil of coupled magnetic resonances analyzed using the equivalent circuit model, and the relationship of the transmission efficiency and the coil parameters got by control variable method through MATLAB. It provides the basis for the optimal design of the coupling coil. Finally, optimization of a specific model was introduced in this paper, with the hope that it will help to achieve an efficient and optimized model.
