Abstract
The power supply device of the present invention supplies power highly reliably by suppressing an increase in costs even when a multiplicity of load groups are present. When operating normally, each of the normal power supply units supplies power via a normal path to each of the load groups. One redundant power supply unit is provided for a plurality of normal power supply units. When any of the normal power supply units fail, the redundant power supply unit continues to supply power to the load group via the redundant path. A diode for connecting the redundant path to the normal path is provided in each normal power supply unit and the redundant paths that are routed through the respective normal power supply units are connected so as to intersect one another between the normal power supply units.
