摘要： A main power supply (13) and a backup power supply (14) have the same set voltage. To prevent electrical power from being supplied from the backup power supply (14) to a load circuit (2), during a normal operation, a power supply control unit (11) gives a standby instruction to the backup power supply (14) so that the backup power supply (14) is on standby at a voltage lower than that of the main power supply (13). When an AC power supply (1) is stopped, the backup power supply (14) is operated at the set voltage and the main power supply (13) is stopped.

摘要： When a result of detection by a current sensor 22 represents the occurrence of an overcurrent, comparators 23 of PSUs 2 transmit a present report indicating that fact to an SP 1. Receiving the present report, an FPGA 12 of the SP 1 turns on a forcible low-power signal. A forcible power saving control circuit 32 of a CPU 3 directly inputs a forcible-low-power-mode signal, turns on the signal, and controls an instruction issuance control unit that is configured to issue an instruction in the CPU 3, so as to immediately decrease the frequency at which the instruction issuance control unit issues instructions. This control is cancelled after the DVFS control circuit 35 has reduced the voltage of power output from a DDC 4 and a clock frequency output from a PLL circuit.
