1. A power transmitting apparatus comprising:

  • a first magnetic resonance coil configured to externally transmit power as magnetic field energy through magnetic resonance;

    a first power transmitting-and-receiving unit configured to supply power to at least the first magnetic resonance coil;

    a second magnetic resonance coil configured to accept the magnetic field energy through magnetic resonance occurring between the first magnetic resonance coil and the second magnetic resonance coil;

    a second power transmitting-and-receiving unit configured to accept the power at least with reference to the second magnetic resonance coil;

    a main power supply; and

    a power supply-management unit configured to select (a) either the power accepted by the second power transmitting-and-receiving unit or power transmitted from the main power supply, and transmit the selected power to the first power transmitting-and-receiving unit, and/or (b) transmit the power accepted by the second power transmitting-and-receiving unit and the power transmitted from the main power supply to the first power transmitting-and-receiving unit in combination.
