Abstract:
A wireless power transmitter including a power supply unit configured to supply an input voltage; a power conversion unit configured to generate wireless power based on a driving signal, generated by the supplied input voltage and a first pulse width modulation (PWM) signal, and transfer the wireless power to a wireless power receiver; and a power transmission control unit configured to receive a voltage value of a battery charged with the wireless power through a wireless network, and generate the first PWM signal based on the voltage value of the battery.
