摘要：An object is to provide a wireless power feeding system using the resonancemethod, which can increase power transmission efficiency. The wireless power feedingsystem includes a power transmission coil electrically connected to a high-frequencypower supply, a power transmission resonance coil for transmitting power by
electromagnetic induction with the power transmission coil, a power reception resonancecoil for exciting high-frequency power by magnetic resonance, a load coil for excitinghigh-frequency power by electromagnetic induction with the power reception resonancecoil, a load, and a variable element. The load includes a microprocessor for controllingthe impedance of the load, a battery charger, and a battery. The battery charger isconfigured to charge the battery with the high-frequency power excited by the load coil.
