Wireless power feeder/receiver and wireless power transmission system
First Claim
1. A wireless power feeder/receiver comprising:
- a power feed/receive coil;
a power feed/receive capacitor to configure a resonance circuit together with the power feed/receive coil;
a coupling coil electromagnetically coupled to the power feed/receive coil;
a power adjustment section performing at least any one of adjustment for AC power to be transmitted from the power feed/receive coil and adjustment for AC power to be received by the power feed/receive coil;
a switching section switching connection of the power feed/receive coil, the power feed/receive capacitor, and the coupling coil to the power adjustment section, the power feed/receive coil, when being switched to connect with the power adjustment section, being connected to the power adjustment section via a coupling transformer; and
a switching control section controlling the switching section.
