<p>PROBLEM TO BE SOLVED: To provide a DC-DC converter system that maintains a long overall operating time at a maximum output by consuming secondary batteries as input sources for respective DC-DC converters to an even level.SOLUTION: The DC-DC converter system includes a monitoring unit 13 for computing an average value of output currents of a plurality of DC-DC converters 121-12n in parallel operation. The DC-DC converters 121-12n each include: a DC-DC converter main circuit 151-15n for outputting predetermined DC power converted from a secondary battery 111-11n; a control device 161-16n for controlling the output current of the corresponding DC-DC converter such that the output current of the corresponding DC-DC converter becomes the average value Iave computed by the monitoring unit 13; and an output circuit 171-17n for outputting the DC power output from the DC-DC converter main circuit 151-15n as a current source to a load.</p> |
