FIG1 is a diagram showing an exemplary configuration of a resonance-type power transfer system according to a first embodiment of the invention
FIG1 is a diagram showing an exemplary configuration of a resonance-type power transfer system according to a first embodiment of the invention. The resonance-type power transfer system includes, as shown in FIG1, a resonance-type transmission power supply device 1, a transmitting antenna (TX-ANT) 2, a receiving antenna (RX-ANT) 3, a receiving circuit 4, and a load 5. The resonance-type transmission power supply device 1 includes an interface power supply (VI-I/F) 6 and an inverter circuit 7. The receiving circuit 4 includes a rectifier circuit (REC) 8 and an interface power supply (Vo-I/F) 9. The resonance-type transmission power supply device 1 and the transmitting antenna 2 form a resonance-type power transmission device, and the receiving antenna 3 and the receiving circuit 4 form a resonance-type power reception device. Note that the power transfer type between the transmitting antenna 2 and the receiving antenna 3 is not particularly limited, and any of a magnetic field resonance-type, an electric field resonance-type, and an electromagnetic induction-type may be used. In addition, the transmitting antenna 2 and the receiving antenna 3 are not limited to contactless antennas such as those shown in FIG1.
