METHOD AND APPARATUS FOR TRANSMITTING MULTI-RADIO POWER USING TIME DIVISION MODE

摘要

The present invention relates to a method and an apparatus for transmitting multi-radio power using a time division mode. According to one embodiment of the present invention, a multi-radio power transmission method for wirelessly transmitting power to a plurality of receivers using a time division mode comprises the steps of: (a) allocating an exclusive power transmission time to each of at least one of a plurality of receivers; and (b) wirelessly transmitting power to each of at least one of the receivers. The method sets a receiving state of an ith receiver in an ON-state during the exclusive power transmission time allocated to the ith receiver, and sets the receiving states of the other receivers except for the ith receiver in an OFF-state. The present invention maintains high and uniform power transmission efficiency with respect to the plurality of the receivers and can wirelessly transmit the power thereto.
