WIRELESS POWER FEEDER AND WIRELESS POWER TRANSMISSION SYSTEM
First Claim
1. A wireless power receiver that receives, at a receiving coil, AC power fed from a feeding coil by wireless based on a magnetic field coupling between the feeding coil and a receiving coil, the receiver comprising:
- the receiving coil; and
an adjustment circuit that receives a first AC power received by the receiving coil, whereinthe adjustment circuit including;
a first conversion circuit that converts the first AC power into DC power; and
a second conversion circuit that converts the DC power into a second AC power of a predetermined frequency,the adjustment circuit outputting the DC power and second AC power through separate channels.

Abstract
Power is transmitted based on magnetic resonance from a feeding coil L2 to a receiving coil L3. An adjustment circuit 104 of a wireless power receiver 118 is supplied with a first AC power received by the receiving coil L3. An adjustment circuit 104 includes a DC circuit 106 and an AC circuit 150. The DC circuit 106 converts the first AC power into DC power. The AC circuit 150 converts the DC power into a second AC power. The adjustment circuit 104 outputs the DC power and second AC power simultaneously or selectively through separate channels.

8. A wireless power transmission system for feeding power by wireless from a feeding coil to a receiving coil based on a magnetic field coupling between the feeding coil and receiving coil, the system comprising:
-
the feeding coil; a plurality of the receiving coils; a power transmission control circuit that supplies AC power to the feeding coil to make the feeding coil feed the AC power to the receiving coils; a first conversion circuit that converts a first AC power received by each receiving coil into DC power; and a second conversion circuit that converts the DC power into a second AC power of a predetermined frequency, the receiving coils including a first receiving coil that outputs the DC power through the first conversion circuit and a second receiving coil that outputs the second AC power through both the first and second conversion circuits.
