PURPOSE:To inhibit report of generation of a secondary failure when a failure occurs at least one device in a power control system including a plurality of power-supply devices. CONSTITUTION:In a power supply control system which contains DC-DC converters 3 and 4 with an output of a rectifying power supply 2 as an input, a signal line 12 for transmitting a failure generation signal connecting these devices is provided. When at least one of these devices fails, it is reported to all other devices using the signal line 12 for performing failure treatment, thus enabling only a report on generation of a primary failure to be given to a power supply control device 1 without giving any report on generation of a secondary failure. |
