Abstract
Provided is a wireless power reception apparatus for wirelessly receiving power from a wireless power transmission apparatus, the wireless power reception apparatus including a reception coil configured to receive power by a harmonic with an n*f0 frequency that is generated through electromagnetic induction with the wireless power transmission apparatus; a matching circuit configured to transfer the harmonic with the n*f0 frequency to a harmonic generator; the harmonic generator configured to generate at least one harmonic with an m*n*f0 frequency by applying a multiplication factor m to the transferred harmonic with the n*f0 frequency; a filter configured to filter the harmonic with the m*n*f0 frequency; and a harmonic transmission coil configured to transmit the filtered harmonic with the m*n*f0 frequency to the wireless power transmission apparatus, and to attenuate the harmonic with the n*f0 frequency that is generated from the wireless power transmission apparatus.
