    • In an electrical power transmission system according to the present invention, a frequency generator outputs electrical power of an electrical signal having approximately the same frequency component as a resonant frequency of a resonant element to the resonant element via a driven element. The resonant element is an element having impedance and capacitance and generates a magnetic field by the electrical signal from the frequency generator. A magnetic field coupling circuit is a circuit having the same resonant frequency as the resonant element and becomes coupled by magnetic field resonance with the resonant element. The magnetic field coupling circuit causes magnetic field coupling even with another resonant element and transmits electrical power from the resonant element to the other resonant element. The other resonant element outputs electrical power transmitted through the magnetic field coupling circuit to a rectifier circuit via a driven element.
    • 在根据本发明的电力传输系统中,频率发生器经由从动元件将具有与谐振元件的谐振频率大致相同的频率分量的电信号的功率输出到谐振元件。 谐振元件是具有阻抗和电容的元件,并且通过来自频率发生器的电信号产生磁场。 磁场耦合电路是具有与谐振元件相同的谐振频率的电路,并且通过与谐振元件的磁场谐振耦合。 磁场耦合电路即使用另一个谐振元件也引起磁场耦合,并将电功率从谐振元件传输到另一谐振元件。 另一个谐振元件通过驱动元件将通过磁场耦合电路传输的电力输出到整流器电路。
