There are provided an apparatus apparatus for transmitting power wirelessly. The apparatus for transmitting power wirelessly may include a boosting unit boosting an input voltage, and an inverter unit inverting the boosted voltage output from the boosting unit to transmit power wirelessly. The inverter unit and the boosting unit are controlled by the same switching element.

A wireless charger optimized for charging efficiency of portable terminals (e.g., mobile phones) of different sizes has a housing including within it laterally spaced side supports and a bottom support for cradling an inserted portable terminal. The side supports and the bottom support are interlocked for coordinated movement such that the bottom support is moved by a predetermined amount according to movements of the side supports. This arrangement optimizes relative placement of the charger's transmitting coil and the portable terminal's receiving coil.

Apparatus for wireless charging

There is provided a wireless charging system, including: a wireless power transmitting module including at least one power transmitter transmitting power and at least one wireless power receiving module receiving the power, wherein the wireless power transmitting module controls the power, which is transmitted to the wireless power receiving modules corresponding to the power transmitters, from the power transmitters, depending on targeted voltage gains of the wireless power receiving modules corresponding to the power transmitters.

Wireless charging system and method for controlling the same

A method of controlling a wireless power transmitter includes actuating the wireless power transmitter to transmit a beacon signal, determining approach of an external object according to a detected change in the beacon signal, and transmitting ping signals having different frequencies responsive to the determined approach of the external object.
