ELECTRICAL POWER TRANSMISSION SYSTEM AND ELECTRICAL POWER OUTPUT DEVICE

摘要

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.
