<p>PROBLEM TO BE SOLVED: To compensate for the voltage drop through a cable.SOLUTION: A power supply system includes: a conversion device which generates a DC supply voltage from an AC supply voltage of an external power supply; and a repeating device which can be connected to the conversion device through the cable and can be connected to electric equipment. The repeating device makes a current, flowing in from the conversion device through a plus line of the cable, flow not to the electric equipment, but to a minus line thereof in a detection period, and makes the current flow to the electric equipment in an electric power supply period, and the conversion device generates the DC supply voltage from the value of the current flowing to the plus line in the detection period and the value of the DC supply voltage in the detection period.</p> |
