A power supply device includes a controller configured to output, to a power converter, a command value to control at least one of a voltage or a current of power output from the power converter, and acquire a measurement value measured by a measurement unit. The controller is configured to, while power conversion operation is being performed by the power converter, change the command value and determine a deterioration of the power converter based on a mode of a change in the measurement value measured by the measurement unit due to a change in the command value.
