1. A resonance power transmitter comprising:
- a source resonance unit comprising a first source resonator transmitting a first power to a first resonance power receiver during a first time period and a second source resonator transmitting a second power to a second resonance power receiver during a second time period;
a path-multiplexer to supply a source power to the first source resonator during the first time period and supply the source power to the second source resonator during the second time period;
a detector to transmit a wake-up signal to at least two resonance power receivers, and detect the first resonance power receiver and the second resonance power receiver; and
a source controller to adjust a level of the first power based on a length of the first time period, and adjust a level of the second power based on a length of the second time period, so that the first power and the second power are transmitted to the first resonance power receiver and the second resonance power receiver in a non-overlapping alternating manner that produces a total power at an average power level.

Abstract
Provided is an apparatus and method that may select a target for a wireless power transmission. A resonance power transmitter may include a source resonance unit including a plurality of source resonators that are each configured to transmit AC power to a resonance power receiver; a path-multiplexer configured to supply the AC power to each of the plurality of source resonators; a detector configured to transmit a wake-up signal to at least one resonance power receiver; and a source controller configured to control the path-multiplexer in order to transmit the AC power to the at least one detected resonance power receiver.

9. A resonance power transmitter comprising:
-
a source resonator comprising a first source resonator transmitting a first power to a first resonance power receiver during a first time period and a second source resonator transmitting a second power to a second resonance power receiver during a second time period; a controller to transmit a wake-up signal to at least two resonance power receivers; and a detector to detect the first resonance power receiver and the second resonance power receiver based on a signal in response to the wake-up, wherein a source power is supplied to the first source resonator during the first time period, and the source power is supplied to the second source resonator during the second time period, and wherein the controller adjusts a level of the first power based on a length of the first time period, and adjusts a level of the second power based on a length of the second time period, so that the first power and the second power are transmitted to the first resonance power receiver and the second resonance power receiver in a non-overlapping alternating manner that produces a total power at an average power level.
