Abstract
A wireless power transmission device, a wireless power transmission control device, and a wireless power transmission method are provided. A coupling frequency between a source resonator and a target resonator is determined A transmission frequency is controlled such that power is transmitted from the source resonator to the target resonator at the coupling frequency. Therefore, it is possible to maintain a high power transmission efficiency without using an additional matching circuit even when a distance between the source resonator and the target resonator is changed.
