WIRELESS POWER TRANSMISSION DEVICE, SUPPLY POWER CONTROL METHOD FOR WIRELESS POWER TRANSMISSION DEVICE, AND METHOD FOR MANUFACTURING WIRELESS POWER TRANSMISSION DEVICE

摘要

A wireless power transmission device (1) supplies power from a power supplying module (2) equipped with a power supplying coil (21) and a power supplying resonator (22) to a power receiving module (3) equipped with a power receiving coil (31) and a power receiving resonator (32) by changing magnetic field. In a supply power control method for the wireless power transmission device (1), the power is supplied with such a value that the driving frequency of the power supplied to the power supplying module (2) does not become the resonance frequencies of the power supplying module (2) and the power receiving module (3). The element values of circuit elements constituting the power supplying module (2) and the power receiving module (3) are used as parameters, and by changing each of the parameters, the input impedance (Zin) of the wireless power transmission device (1) is set to adjust the power to be supplied.
