Abstract:
A power transmission device according to one embodiment, includes a first power transmission resonator configured to wirelessly transmits power; a second power transmission resonator configured to wirelessly transmits power; a first power supply configured to output AC power to the first power transmission resonator; and a second power supply configured to output AC power having a frequency different from that of the first power supply to the second power transmission resonator. An operating band of the first power transmission resonator includes the frequency of the first power supply and does not include the frequency of the second power supply. An operating band of the second power transmission resonator does not include the frequency of the first power supply and includes the frequency of the second power supply.
