Abstract:
A wireless power transmitter for transmitting power in a wireless manner by forming a wireless power signal and a wireless power transfer method thereof are capable of optimizing transmission efficiency for a plurality of wireless power receivers, by deciding an optimal transmission parameter (especially, a frequency corresponding to the wireless power signal or a resonant frequency) for the plurality of wireless power receivers based on control errors received from the plurality of wireless power receivers, respectively, via respective time slots allocated to the plurality of wireless power receivers.
