Abstract
A power supply device includes: a power supply; a conversion module including a plurality of conversion units configured to perform voltage conversion of power supplied by the power supply, the plurality of conversion units being electrically connected in parallel to each other; and a change unit that an operation number, which is the number of the conversion units performing the voltage conversion. The change unit prohibits a change to an operation number in which current imbalance occurs between the conversion units performing the voltage conversion.
