Abstract
The present invention discloses a wireless power transfer system having positioning function, and a positioning device and a method therefor. In the positioning method, a power transmission side keeps generating a stable power; a power receiving side is moved relatively to the power transmission side and generates a corresponding induced voltage. An indication signal related to the induced voltage is generated by detecting the induced voltage, and the indication signal provides a suggestion to a user as to how the power receiving side should be moved relatively to the power transmission side to be closer to an optimal power transfer position.
