1. A wireless power transmitter comprising:

  • 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 the 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 and an amount of power that can be output by the battery module.
