POWER CONVERTER, CONTROL SYSTEM FOR POWER CONVERTER, ELECTRONIC DEVICE, MACHINE LEARING DEVICE, AND CONTROL METHOD OF COOLING FAN

摘要

The power conversion device (2) includes a cooling fan (8), a cooling fan control unit (10) for controlling the driving amount of the cooling fan (8), and an electrolytic capacitor whose life varies with the driving amount of the cooling fan (8). And (5). The cooling fan control unit (10) controls the driving amount based on the relationship between the driving amount, the life of the cooling fan (8), and the life of the electrolytic capacitor (5).
