PURPOSE: A wireless power receiver is provided to promote transmission efficiency and to prevent unnecessary heating of a wireless power receiver. CONSTITUTION: A non-radiative electromagnetic wave receiving unit(210) receives a non-radiative electromagnetic wave in resonance. A poly-phase signal separator(220) separates poly-phase signals from the received non-radiative electromagnetic wave. A poly-phase signal rectifier(230) rectifies the separated poly-phase signals. A DC/DC converter(240) converts the rectified DC power into usable power to a loading unit.
