<P>PROBLEM TO BE SOLVED: To solve the problem, wherein it is not possible to control the operating state and the stopped state of an individual power-source module so that it becomes an optimum redundant configuration, with respect to the maximum power consumption of a load, in a power source device including power source modules respectively having different power source capacities. <P>SOLUTION: The power source device is configured such that: a plurality of power source modules are put in an operating state or a stopped state, according to a power-source state instruction for instructing an operation or a stop; each power source module supplies power to a load; on the basis of each power-source capacity value of the plurality of power source modules and the maximum-power-consumption value of the load, the power-source state instruction is outputted after determining the operation or the stop of each power source module so as to prevent the total of the power-source capacity values of the remaining power source modules, excluding the predetermined number of redundant power source modules, from becoming less than the total of the maximum-power-consumption values. <P>COPYRIGHT: (C)2010,JPO&INPIT |
