摘要:
A wireless power transmission system includes a charging and path controller configured to supply, to a battery module, power generated by a solar cell module, or power generated by an alternating current-to-direct current (AC/DC) converter, based on a control signal; a power converter configured to receive power from the battery module and generate a supply power to be supplied to a target device from power received from the battery module using a resonant frequency; a source resonator configured to receive the supply power from the power converter and transmit the supply power received from the power converter to the target device; and a control/communication unit configured to generate the control signal of the charging and path controller based on an amount of the power generated by the solar cell module and an amount of power that can be output from the battery module.
摘要:
A wireless power transmission and charging system and method are provided. The wireless power may refer to energy that may be transferred from a wireless power transmitter to a wireless power receiver.

摘要:
An apparatus and method for performing communication in a wireless power transmission system are provided. The apparatus includes a channel search unit configured to search for communication channels other than a channel used in wireless power transmission, and measure state information of the communication channels. The apparatus includes a channel determining unit configured to determine a communication channel available for communication with a target device based on the measured state information. The apparatus includes a communication unit configured to transmit an access instruction to the target device using the determined communication channel. The apparatus includes a controller configured to determine whether to communicate with the target device using the determined communication channel based on whether a response signal corresponding to the access instruction is received.
