摘要：

谐振耦合式电能无线传输系统利用磁场通过近场传输,具有辐射小、效率高、传输距离远且方向性强等特点。文中采用等效简化电路方法分析了谐振式电能无线传输系统串串模型的间距、工作频率、负载等参数对传输效率和功率的影响及内在关系,进一步推导出其计算模型。在间距和负载一定的条件下,通过Matlab仿真得到效率最优与功率最大时的工作频率相一致,输出功率对工作频率的变化敏感度更高这一规律。此外,设计了一套串串式结构的谐振式电能无线传输装置,通过实验验证了理论分析的正确性,为研究电能无线传输提供了参考。

Abstract:

Wireless power transmission system via resonance coupling displays its superiority in its low radiation,high efficiency,long transmission distance and directional characteristics by using near-field magnetic transmission.The paper uses a new method to simplify the equivalent circuit to analyze the impact of wireless power transmission system based on the resonance coupling series-series model parameters of distance,frequency and load on the transmission efficiency and power and the inner relation,to deduce the calculation model.Under certain load conditions and the spacing,the optimal working frequency and the efficiency at the maximum power of working frequency is consistent through Matlab simulation.The rule is found the output power to be more sensitive to the operating frequency.A wireless power transmission device based on the resonance coupling is designed.The correctness of theoretical analysis is verified by experiment,to provide a useful reference for studying the power wireless transmission.

Key words: wireless power transmission;resonant coupling;primary coil;series-series model
