POWER TRANSMMISSION APPARATUS, POWER TRANSMISSION/RECEPTION APPARATUS, AND METHOD OF TRANSMITTING POWER

摘要

A power transmission apparatus includes: a power source; a power transmission coil that transmits electric power supplied from the power source outward as magnetic energy through magnetic resonance; a peak searching unit that searches for a drive frequency at which the magnetic energy transmitted outward has a peak; a peak split detector that detects splitting of the drive frequency at which the magnetic energy transmitted outward has a peak; a selection unit that selects a higher-frequency side frequency among split drive frequencies generated by the splitting; and a drive unit that drives the power transmission coil using the frequency selected by the selection unit.
