Wireless power transmission apparatus for performing non-contact transmission by electromagnetic induction
Abstract:
A wireless power transmission apparatus is provided for performing non-contact transmission of power by electromagnetic induction, and includes a power transmitter performing frequency conversion; a power transmitting antenna connected to the power transmitter; and a first resonance capacitor connected between the power transmitter and the power transmitting antenna, and resonating with the power transmitting antenna to pass the power transmission frequency of the power transmitter. The wireless power transmission apparatus includes a power receiving antenna arranged to oppose the power transmitting antenna; a power receiver connected to the power receiving antenna, and performing rectification and smoothing; and a second resonance capacitor connected between the power receiving antenna and the power receiver, and resonating with the power receiving antenna to pass the power transmission frequency of the power transmitter. The wireless power transmission apparatus includes a filter connected between the second resonance capacitor and the power receiver, and reflecting higher harmonics generated by the power receiver.
