摘要

PROBLEM TO BE SOLVED: To realize highly efficient power transmission while controlling the power set in a power transmission beam so as not to exceed the power receiving capacity of a power receiving device. A power transmission device according to one aspect of the present disclosure includes a control unit that controls a power transmission unit that performs wireless power transmission, and the control unit transmits a first power transmission beam in which a first electric power is set to the power transmission unit. The second power available in the wireless power supply for the power receiving device is determined by referring to the means for radiating and the feedback information regarding the reception result of the first power transmission beam in the power receiving device and the power receiving capacity of the power receiving device. The first power is weaker than the second power. [Selection diagram] FIG. 9
