<P>PROBLEM TO BE SOLVED: To provide a parallel operation power supply apparatus that achieves higher performance. <P>SOLUTION: The parallel operation power supply apparatus is configured so that a number of driving converters control unit 22 determines the value (total current value/number of driving converters), obtained by dividing the total input current value of a power supply apparatus 10 by the number of driving DC-DC converters 13a-13c, to be most approximate to the rated current value of current sensors 24a-24c. The operation of the DC-DC converters 13a-13c is controlled so that the current value handled by the current sensors 24a-24c approaches closer to the rated current value still more, thereby the controllability is enhanced by improvement in detection accuracy of the current sensors 24a-24c resulting in a power supply apparatus 10 exhibiting higher performance. <P>COPYRIGHT: (C)2010,JPO&INPIT |
