Abstract
Official abstract text for this publication.
Power is fed from a feeding coil to a receiving coil L 3 by magnetic resonance. The receiving coil L 3 and a capacitor C 3 are connected in series to constitute a receiving coil circuit. A loading coil L 4 electromagnetically coupled to the receiving coil L 3 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 C 3 allows heat generated from the rectification circuit 142 to escape to the first flat plate electrode 132.
First claim
Opening claim text (preview).
What is claimed: 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 r…
