WIRELESS POWER TRANSFER DEVICE, SUPPLIED-POWER CONTROL METHOD FOR WIRELESS POWER TRANSFER DEVICE, AND WIRELESS-POWER-TRANSFER-DEVICE MANUFACTURING METHOD |
摘要 |
A wireless power transmission apparatus, a supply power control method, and a manufacturing method of the wireless power transmission apparatus, with which supply power is controlled by adjusting the resonance frequency of a coil of a power-supplying device and/or the resonance frequency of a coil of a power-receiving device while power transmission efficiency is maintained, are provided. As a supply power control method for a wireless power transmission apparatus 1 which supplies power from a power-supplying module 2 including a power-supplying resonator 22 to a power-receiving module 3 including a power-receiving resonator 32 by changing a magnetic field, power supplied to a power-supplied electronic device 10 is controlled by setting an input impedance Z in of the wireless power transmission apparatus 1 by adjusting the resonance frequency of at least one of a power-supplying resonator 22 and a power-receiving resonator 32. |
