Wireless power supply apparatus

Abstract

An embodiment of the present invention relates to a wireless power supply apparatus, which has a power pickup core formed to wrap a corner of a power pickup cable to increase an inductive electromotive force induced in a power pickup unit, has a power feeding unit configured to transfer a magnetic flux by only a power feeding cable without a power feeding core, to reduce the enormous cost for materials required to fabricate the power feeding core and thus enhance the price competitiveness, and reduce the weight and volume thereof and thus simplify the installation thereof, and has the power pickup core configured to include a plurality of power pickup core members, to reduce the weight and volume of the power pickup unit and thus increase the operational efficiency of the vehicle under which the power pickup unit is mounted.
