The present invention relates to a design of a wireless power transmission system and an optimal resonant frequency control method applied to the system, and provides a wireless power transmission system and an optimal resonant frequency control method applied to the system, by designing the power transmission part to match the frequency control range and designing the quality factor of the resonance unit of the power receiving part to be low, the difference of the power receiving performance in the control frequency range is small, and even if the resonance frequency of the wireless power transmission system arranged in a metal environment changes, the wireless power transmission system can still work normally. Power can be stably received, and a system frequency can be easily and quickly controlled to search for and find an optimal resonant frequency.

    本发明涉及一种无线电力传输系统的设计及应用于该系统的最佳谐振频率控制方法,并且提供一种无线电力传输系统及应用于该系统的最佳谐振频率控制方法,其中,通过将输电部设计为匹配频率控制范围的方法及通过将受电部的谐振单元的品质因数设计得较低,使得在控制频率范围内电力接收性能的差异不大,即使设置于金属环境的无线电力传输系统的谐振频率发生变化,也能够稳定地接收电力,并且可以容易且快速地控制系统频率以搜索并找到最佳谐振频率。
