    Abstract: A method for multiple wireless power transfer, capable of transmitting power wirelessly to multiple receivers, by using a time division scheme, includes the steps of: (a) allotting exclusive power transmission time for at least one of the multiple receivers; and (b) transmitting the power wirelessly to each of the at least one of the receivers; wherein, during the exclusive power transmission time allotted to an i-th receiver, which is one of the multiple receivers, the receiving state of the i-th receiver is set to ON and those of the other receivers to OFF. In accordance with the present invention, the following effects can be achieved: the PTE of the multiple receivers may be increased and the PTE of each of the receivers may be kept similarly because the power is transmitted only to one receiver by using the time division scheme and thus interference among multiple receivers is eliminated.
