Abstract
It is aimed to provide a power supply device and a power supply system which enable consumers to freely choose electrical power and specify transmission sources when receiving electrical power, and enable parties involved in transactions (power supply side and power receiving side) to reliably and safely perform transmission between them. There are provided a power supply device and a power supply system. The power supply device includes a baseband unit that generates a power signal, a modulation processing unit that modulates the power signal generated by the baseband unit to impart a code thereto for specifying a transmission source of the power signal and generates a modulated signal that can be demodulated by a power receiving device, and a transmission unit that transmits the modulated signal generated by the modulation processing unit.
