Wireless power receiver and wireless power transmission system
First Claim
1. A wireless power receiver including a receiving coil for wirelessly receiving AC power fed from a feeding coil by using a magnetic field resonance phenomenon between the feeding coil and the receiving coil, the receiver comprising:
- a receiving coil circuit that includes a capacitor comprising first and second flat plate electrodes facing each other and the receiving coil; and
a loading circuit that includes a loading coil that is magnetically coupled to the receiving coil to receive the AC power from the receiving coil and a load to which the AC power is supplied from the loading coil,a heating element included in the loading circuit being placed directly on one of the first and second flat plate electrodes, whereinthe receiving coil is wound around the capacitor, andthe capacitor is disposed at a center area substantially equidistant from the receiving coil wounding around the capacitor.

Abstract
Power is fed from a feeding coil to a receiving coil L3 by magnetic resonance. The receiving coil L3 and a capacitor C3 are connected in series to constitute a receiving coil circuit. A loading coil L4 electromagnetically coupled to the receiving coil L3 is connected to a load through a rectification circuit 142 to constitute a loading circuit. Placing the rectification circuit 142 on a first flat plate electrode 132 of the capacitor C3 allows heat generated from the rectification circuit 142 to escape to the first flat plate electrode 132.
