WIRELESS POWER TRANSMISSION APPARATUS AND WIRELESS POWER RECEIVING APPARATUS

摘要

PURPOSE: A wireless power transmission apparatus and wireless power receiving apparatus are provided to maximize a shielding effect by reducing the size of a magnetic field exposed to surroundings since a second cut-out part is added to sides of a reception coil and a transmission coil. CONSTITUTION: A cut-out part blocks a magnetic field not to be exposed to the outside from a transmission coil(L1) and/or a reception coil(L2). The cut-out part includes a first cut-out(S10) and a second cut-out part(S30) formed on the side of a coil. The coil includes at least one of the transmission coil and the reception coil. The first cut-out is prepared in order to have an interval(d13) separated approximately 1.0mm from one side of the coil. The second cut-out is prepared in order to have an interval(d15) maximally separated 1.9mm from the coil.
