Abstract
A wireless power relay apparatus includes: a first antenna configured to wirelessly receive an alternating current (AC) power signal of a first frequency from a wireless power transmission apparatus; a rectifier configured to convert the received AC power signal into a direct current (DC) power; a storage device configured to store electric energy of the DC power output from the rectifier; a power oscillator configured to generate an AC power signal of a second frequency based on an output current of the rectifier and electric energy of a DC voltage stored in the storage device; and a second antenna configured to transmit the AC power signal of the second frequency to a wireless power reception apparatus.
