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 including a power-supplying resonator to a power-receiving module including a power-receiving resonator by changing a magnetic field, power supplied to a power-supplied electronic device is controlled by setting an input impedance Zin of the wireless power transmission apparatus by adjusting the resonance frequency of at least one of a power-supplying resonator and a power-receiving resonator.
