WIPO Patent Application WO/2013/118555
Kind Code:
A1
Abstract:
A wireless power supply system (100) comprises a power transmitting device (110) and a power receiving device (130) that receives power supplied from the power transmitting device (110) by a magnetic field resonance method. The power transmitting device (110) includes: a power supply (111) for generating power; a power transmitting unit (113) for transmitting the power generated by the power supply (111) to the power receiving device (130); a reflected power detection unit (112) for detecting the value of reflected power obtained by the power transmitting unit (113); and a control unit (115) for determining the state of load in the power receiving device (130) from the value of reflected power detected by the reflected power detection unit (112).
