Abstract

An electric power receiving device according to the invention receives an electric power from a primary coil, with which a first alternating voltage is applied and through which a first alternate current flows. The device includes an electric power receiving section and a reducing-voltage generating section. The receiving section includes a secondary coil electromagnetically coupled to the primary coil and a capacitor connected to the secondary coil, and generates a second alternating voltage based upon the first alternating current. The generating section generates a reducing-voltage and applies the reducing-voltage to the receiving section, the reducing-voltage being capable of reducing a reactance voltage generated in the receiving section by a second alternating current generated in the receiving section due to the second alternating voltage, and the reducing-voltage being approximately equal to the second alternating voltage in frequency.
