Abstract: An apparatus and a method for charge control are provided. The apparatus for charge control may include an integrated direct current-to-direct current (DC/DC) converter configured to step up an output voltage level of a load to be greater than or equal to a supply voltage level set in a power amplifier, and the power amplifier configured to convert a direct current (DC) voltage stepped up by the integrated DC/DC converter into an alternating current (AC) voltage based on a resonant frequency, and to amplify the converted AC voltage. The apparatus for charge control may include a rectification unit configured to convert an AC power received wirelessly into a DC power; and a DC/DC converter configured to step down a voltage level of the DC power to a voltage level required by a load in the receiving mode.

Abstract: A wireless power transmission method includes searching for one or more routes to be used to transmit power to a reception resonator through one or more relay resonators, and converting the routes to respective one or more two-port networks. The method further includes calculating a transmission efficiency of each of the routes based on the two-port networks, and selecting a route with a highest transmission efficiency from the routes. The method further includes wirelessly transmitting power to the reception resonator through the selected route.
