装置。 In an uninterruptible power supply device in which a storage battery for supplying load power during a power outage is connected to the output side of a power converter, and the output voltage of the power converter is restored with a temporal gradient when power is restored, the power converter current detection means for detecting the current flowing through the power converter; and a soft start for controlling the power converter so that the time slope until the current detection means detects the current is larger than the time slope thereafter. An uninterruptible power supply characterized by comprising a control means.
