Resonant coupling type power transmission system, the resonance type power transmission apparatus and a resonance type power transmission device

摘要

Resonance type power transmission device 1 having resonance type power supply 11 that supplies power, and resonance type transmission antenna 13 that transmits power supplied from resonance type power supply 11, and power transmitted by resonance type transmission antenna 13 are received. A resonance type reception antenna 21, and a resonance type power reception device 2 having a reception circuit 23 that supplies power received by the resonance type reception antenna 21 to a load, the resonance characteristic value of the resonance type power supply 11, and the resonance type transmission antenna The characteristic impedance of each functional unit was set so as to correlate the resonance characteristic value of 13 and the resonance characteristic value of the resonant power receiving apparatus 2.
