1. A wireless power receiver configured to receive wireless power, the wireless power receiver comprising:

  • a resonant reception unit configured to receive wireless power by a resonance scheme at a second frequency;

    an inductive reception unit configured to receive wireless power by an induction scheme at a first frequency; and

    a power processing unit configured to process wireless power received at the resonant reception unit and the inductive reception unit;

    wherein when the wireless power is received by the induction scheme, a current flowing in the inductive reception unit is greater than a current flowing in the resonant reception unit, and when the wireless power is received by the resonance scheme, a current flowing in the resonant reception unit is greater than a current flowing in the inductive reception unit,wherein the resonant reception unit comprises a second circuit comprising at least one second coil an at least one fourth capacitor, the inductive reception unit comprises a first circuit comprising at least one first coil and at least one first capacitor, andwherein the first circuit, the second circuit, and the power processing unit are connected in parallel.
