More Information
Summary:A wireless power transmission device, configured to transmit AC power to a power receiving coil of a wireless power reception, and that can curb an increase in production costs and curb destabilization of the power which is received by a wireless power reception device with a decrease in quality of wireless communication includes: power transmitting coil that is magnetically coupled to the power receiving coil; power transmitting circuit that is configured to supply an AC voltage to the power transmitting coil; transmission-side communication unit that is configured to perform wireless communication with the wireless power reception device; measuring unit that is configured to measure a characteristic value of the wireless communication; and control circuit that is configured to control the AC voltage which is supplied from the power transmitting circuit to the power transmitting coil on the basis of the characteristic value measured by the measuring unit.
