  "textContent": "A wireless power transmission device (110), a wireless power transmission control device, and a wireless power transmission method are provided. A coupling frequency between a source resonator (111) and a target resonator (121) is determined. A transmission frequency is controlled such that power is transmitted from the source resonator (111) to the target resonator (121) 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 (111) and the target resonator (121) is changed.",
