摘要： In the present invention, junction capacitance is increased by stabilizing the junction capacitance of rotating electrodes such that a short circuit does not occur between the electrodes. Provided is a rotating electrode unit comprising a rotor electrode unit in which one or more rotor electrodes and one or more rotor spacers are alternately stacked, and a stator electrode unit in which one or more stator electrodes and one or more stator spacers are alternately stacked, wherein the rotating electrode unit is configured such that when the rotor electrodes are power transmitting electrodes, the stator electrodes are power receiving electrodes, when the rotor electrodes are power receiving electrodes, the stator electrodes are power transmitting electrodes, the rotor electrode unit and the stator electrode unit are combined in a nesting arrangement so as to be mutually rotatable, at least the outer peripheral section of the rotor electrodes is constituted by a member comprising a magnetic body, and the stator spacers have a magnet which attracts the outer peripheral section of the rotor electrodes via magnetic force.

摘要： An electric power supply system includes an electric power transmission track that transmits electric power from an AC power source having a predetermined wavelength, an electric power reception unit, and a DC track that is used for transmitting DC electric power to the electric power transmission track. The electric power reception unit includes an electric power reception electrode, and moves along the electric power transmission track. The electric power reception unit forms junction capacitance by using the electric power transmission electrode and the electric power reception electrode, thereby receiving electric power from the electric power transmission track and supplies the received electric power to a load. The electric power transmission track includes a plurality of unit sections which are arranged repeatedly, and each of the plurality of unit sections has a length based on the predetermined wavelength and generates a standing wave from the AC power source.
