| 摘 要： | 对谐振耦合电能无线传输系统进行了理论推导，得出在等效阻抗虚部为零时系统达到谐振状态，传输效率可达到最大的结论，并用MATLAB仿真得出在频率分裂的情况下谐振频率与传输距离之间的关系曲线，用实验数据验证了结论的正确性。

| Abstract: | A resonant coupling wireless power transfer system will reach the resonant state when the imaginary part of the equivalent total input resistance is zero, and at the same time the system has the maximum transmission efficiency. The relationship curve between the transmission distance and the resonance frequency is further simulated with MATLAB when bifurcation phenomena occur. Finally, above conclusions are validated by physical experiments. |
