RESONANCE COUPLING POWER TRANSMISSION SYSTEM, RESONANCE COUPLING POWER TRANSMISSION DEVICE, AND RESONANCE COUPLING POWER RECEPTION DEVICE

摘要

A resonant coupling power transmission system includes a resonance type power transmission device 1 having a resonance type power supply 11 to supply power, and a resonance type transmission antenna 13 to transmit the power supplied by the resonance type power supply 11, and a resonance type power reception device 2 having a resonance type reception antenna 21 to receive the power transmitted by the resonance type transmission antenna 13, and a reception circuit 23 to supply the power received by the resonance type reception antenna 21 to a load, and the characteristic impedance of each of the functional units is set in such a way that there is provided a correlation among the resonance characteristic value of the resonance type power supply 11, that of the resonance type transmission antenna 13, and that of the resonance type power reception device 2.
