POWER SUPPLY DEVICE

WIPO Patent Application WO/2014/030440

A1

A power transmission unit is configured by arranging a plurality of resonators such that the resonators one-dimensionally or two-dimensionally form a periodic structure, and transmits power by radio by propagating power to adjacent resonators by a resonance action, and leaking an electromagnetic field to the surroundings. A power supply unit supplies power to one or more of the resonators of the power transmission unit. A power reception unit receives the transmitted power from the power transmission unit. Among the resonators which form the one-dimensional or two-dimensional periodic structure of the power transmission unit, resonators at ends are each loaded with a capacitive element.
