CONTROL DEVICE, CONTROL METHOD, AND WIRELESS POWER TRANSFER DEVICE

WIPO Patent Application WO/2015/001673

A1

[Problem] To allow control that, using a simple architecture, increases power transfer efficiency. [Solution] In a control device that serves as an embodiment of this invention, a transmitted-power-information acquisition unit acquires transmitted-power information that represents one or more of the following: a first power at a first location in a power-transmitting unit that transmits power wirelessly; a first voltage at said first location; and/or a first current at said first location. A received-power-information acquisition acquires received-power information that represents one or more of the following: a second power at a second location in a power-receiving unit that receives power from the power-transmitting unit; a second voltage at said second location; and/or a second current at said second location. On the basis of the transmitted-power information and the received-power information, a transfer-state acquisition unit acquires a parameter that represents the state of the power transfer being performed from the power-transmitting unit to the power-receiving unit. In accordance with said parameter, an adjustment unit selects and executes either a power-transmission adjustment process that adjusts the amount of power being transmitted by the power-transmitting unit or an impedance adjustment process that adjusts the impedance of the power-receiving unit.
