Abstract
A power conversion device includes a cooling fan, a cooling fan control unit that controls the drive amount of the cooling fan, and an electrolytic capacitor whose life varies according to the drive amount of the cooling fan. The cooling fan control unit controls the drive amount based on the relationship between the drive amount, the life of the cooling fan, and the life of the electrolytic capacitor.
