Title:
ロードインピーダンス決定装置とその方法、無線電力伝送装置とその方法、及び電力が無線伝送される端末機
Document Type and Number:
Japanese Patent JP5681995
Kind Code:
B2
Abstract:
A load impedance decision device, a wireless power transmission device, and a wireless power transmission method are provided. At least one of a distance and an angle between two resonators may be measured. A load impedance may be determined based on at least one of the measured distance and the measured angle. When the distance between the two resonators changes, a high power transfer efficiency may be maintained without using a separate matching circuit. Where the load impedance is determined, a test power may be transmitted. Depending on a power transfer efficiency of the test power, the load impedance may be controlled and power may be wirelessly transmitted from the source resonator to the target resonator.
