<P>PROBLEM TO BE SOLVED: To provide a power supply system capable of shortening a period when communication is not performed when an electric device is switched between an on-state and an off-state. <P>SOLUTION: Separating sections equipped on a DC outlet (DC outlet 131, hook sealing 132) and on a DC device 102 separate a voltage from a DC power supply section 101 into a DC voltage and a communication signal. Capacitors equipped on the DC outlet and on the DC device 102 are charged by DC power from the DC power supply section 101 when the DC device 102 is in an off-state. When a setting operation for switching the DC device 102 from an off-state to an on-state is executed, a voltage applied to a main function unit of the DC device 102 becomes instantly higher and ringing is generated in the applied voltage and a voltage on a DC power supply line Wdc. However, the ringing can be released by charging/discharging of the capacitors, so that the actual applied voltage to the main function unit and the actual voltage on the DC power supply line Wdc may reduce the ringing generation period. <P>COPYRIGHT: (C)2009,JPO&INPIT |
