Abstract
A power receiving apparatus includes: a resonance element having a specific resonance frequency and adapted to couple in a non-contacting relationship to a different resonance element through a resonance relationship; a rectification section configured to rectify ac current of the resonance frequency in response to energy received by the resonance element; and a switching section configured to cut off a supplying path of the ac current from the resonance element to the rectification section; the resonance element maintaining the coupling state through the resonance relationship to the different resonance element also when the supplying path of the ac current to the rectification section is blocked by the switching section.
