Abstract
A contactless power feed apparatushas a relay circuitrelaying power transmitted from a power transmission deviceto a power reception devicein a contactless manner. The power transmission devicehas: a transmission coiltransmitting AC power to the relay circuit. The relay circuithas: a first coil, electromagnetically coupled with the transmission coiland receiving the AC power from the transmission coil; a second coil, transmitting the AC power to the power reception device; and a resonant capacitor, resonating with the AC power supplied to the transmission coiltogether with the first and second coils. The power reception devicehas: a resonant circuit, having a reception coilreceiving AC power from the second coilby being electromagnetically coupled with the second coilof the relay circuit
