NON-CONTACT POWER SUPPLYING DEVICE AND NON-CONTACT POWER SUPPLYING METHOD

WIPO Patent Application WO/2010/101078

A1

A non-contact power supplying device is provided with: a resonating means set at a predetermined resonant frequency for receiving power; a resonating means set at the same resonant frequency as said frequency for supplying power; an oscillating means which inputs alternating current power to the resonating means for supplying power; an impedance detecting means which detects an impedance on the power supplying side within a predetermined frequency range; and a variable frequency means which sets the frequency of the alternating current power. The oscillating means supplies power to the resonating means for receiving power so as to provide resonance between the resonating means for receiving power and the resonating means for supplying power, and the variable frequency means sets the frequency of the alternating current power corresponding to the impedance value detected within the predetermined frequency range by means of the impedance detecting means.
