Abstract

The present disclosure describes apparatuses, methods, and systems for wireless power transfer. Each of transmission and reception apparatuses have an alignment coil (DC coil) in addition to a wireless power transmitter/receiver coil (AC coil). At least one of the transmission and reception apparatuses is movably coupled to a support frame that allows the respective transmission and reception apparatus to move there-along to align itself with the other of the transmission and reception apparatus. Transmission and reception apparatuses are thus configured to perform self-position-correction.
