Uninterruptible Power Supply System And Uninterruptible Power Supply Device

Abstract: An uninterruptible power supply device (U) is provided with at least one power converter (1, 4, 5), a plurality of processors (7-12), a memory (15), and a memory access controller (13). The first processor (7) controls the at least one power converter (1, 4, 5) on the basis of information read from the memory (15), and writes control information in the memory (15). The second processor (8) measures a current and voltage input/output to/from at least one power converter (1, 3, 5), and writes measurement information in the memory (15). The third processor (9) exchanges information with other uninterruptible power supply devices and external devices, and writes reception information in the memory (15). The plurality of fourth processors (10) respectively generate a plurality of sets of trace data from the information stored in the memory (15). Trace conditions for generating corresponding trace data are set in advance in each of the plurality of fourth processors (10). Each of the plurality of fourth processors (10) stores the trace data generated according to the corresponding trace conditions in an external storage device.
