Abstract

Official abstract text for this publication.

A wireless power transmission apparatus for high efficiency energy charging, includes a resonator configured to transmit power, and a power supply unit configured to supply power to the resonator. The apparatus further includes a first switching unit configured to connect the resonator to the power supply unit, and disconnect the resonator from the power supply unit, and a controller configured to control the first switching unit based on an amount of current flowing into the resonator.

First claim

Opening claim text (preview).

What is claimed is: 1 . A wireless power transmission apparatus for high efficiency energy charging, the apparatus comprising: a resonator configured to transmit power; a power supply unit configured to supply power to the resonator; a first switching unit configured to connect the resonator to the power supply unit, and disconnect the resonator from the power supply unit; and a controller configured to control the first switching unit based on voltage applied to an input resistor of the power supply unit. 2 . The apparatus of claim 1 , wherein the controller comprises a current sensor configured to sense the amount of the current based on the voltage applied to the input resistor. 3 . The apparatus of claim 2 , wherein: the current sensor comprises a comparator configured to compare the voltage applied to the input resistor to predetermined voltage corresponding to an amount of predetermined current; and the controller is configured to control a turning on and off of the first switching unit based on a result of the comparing. 4 . The apparatus of claim 1 , wherein the controller is configured to turn off the first switching unit in response to the voltage applied to the input resistor being greater than or equal to a reference voltage. 5 . The apparatus of claim 1 , wherein the first switching unit comprises: a transistor disposed between the power supply unit and the resonator; and a diode connected in series to the transistor.
