Abstract:
1. A control apparatus for controlling a first and a second power supply units and converters connected to respective outputs of the power supply units, the power supply units generating a plurality of voltages and supplying a storage device with the generated voltages through the respective converters, the control apparatus comprising: a determination unit for determining whether an abnormality occurs in a first voltage having a first given voltage value and a second voltage having a second given voltage value that the first power supply unit generates, upon the second power supply unit failing to supply the first voltage and the second voltage; and an instruction unit for instructing the converter connected to the first power supply unit to generate the first voltage having the first given voltage value to supply the generated first voltage to the storage device on the basis of the second voltage that the first power supply unit generates, upon the abnormality occurring in the first voltage of the first power supply unit, and instructing the converter connected to the first power supply unit to generate the second voltage having the second given voltage value to supply the generated second voltage to the storage device on the basis of the first voltage that the first power unit generates, upon the abnormality occurring in the second voltage of the first power supply unit, wherein the first power supply unit and the second power supply unit have a redundant configuration.
