| 发明名称 | Wireless power feeding system and wireless power feeding method | ||
| 摘要 | A wireless power feeding system capable of long distance and highly efficient space transmission of power is provided. A wireless power feeding system includes a power transmitter, a power receiver, and a power receiving body. The power transmitter generates electromagnetic waves. The power receiver is supplied with power by means of the electromagnetic waves received from the power transmitter using a magnetic field resonance phenomenon. The power receiving body is inserted into an electromagnetic field created by the power transmitter and the power receiver, and receives power by means of the electromagnetic field. | ||

| 主权项 | 1. A wireless power feeding system comprising: a power transmitter that generates electromagnetic waves; a power receiver that is supplied with power by means of the electromagnetic waves received from the power transmitter using an electric field or magnetic field resonance phenomenon; and a power receiving body that receives power transmitted between the power transmitter and the power receiver by electromagnetic induction, wherein a resonant frequency of the power receiving body is different from resonant frequencies of the power transmitter and the power receiver. | ||
