  • Publication number: 20210296940
    Abstract: According to one embodiment, a power supply apparatus includes a power transmission controller and a receiver. The power transmission controller transmits a first power transmission signal for power supply. The receiver receives first information on a second power transmission signal from a first power supply apparatus. The second power transmission signal is transmitted by the first power supply apparatus for power supply. The power transmission controller determines at least one of a first time at which the first power transmission signal is transmitted, a first direction in which the first power transmission signal is transmitted, or a first power level of the first power transmission signal, using the first information.
