Abstract: A power transmitting unit (PTU) transmits a power wirelessly based on a location of a power receiving unit (PRU). The PTU determines whether the PRU is located within a charging area of the PTU based on frequency information corresponding to an inflection point detected on a curve of electrical characteristics of a resonator of the PTU.
