Abstract
The present invention is intended to prevent the flow of a large input current into a DC/DC converter, to which power is fed from a power supply, before a supply voltage delivered from the power supply reaches a rated output voltage. A control unit included in the DC/DC converter includes a steady state detection block that detects a condition in which an input voltage to be applied to the DC/DC converter has been stabilized, and inhibits the power feed from the DC/DC converter until the input voltage delivered from a power supply in a preceding stage is stabilized.
