AI Technical Summary
Technical Problem
Existing power conversion devices do not effectively notify users of the impending forced operation stop due to increased temperature in the cooling structure, which can disrupt continuous operation and maintenance planning.
Method used
A power conversion device equipped with a cooling structure, blower, and estimation section that predicts the operable time until the cooling structure reaches a critical temperature, using temperature measurement data to notify users of the impending stop.
Benefits of technology
Enables timely notification of the operation stop, allowing for better operational planning and maintenance of the power conversion device.

Abstract
To provide an electric power conversion device, an information processing device, and an information processing method capable of notifying a user of a time to forcibly stop operation of the electric power conversion device due to a temperature rise of a cooling structure section.SOLUTION: An electric power conversion device has a power device (a semiconductor diode SD and a semiconductor switch SW), a cooling structure section 190 for heat dissipation of the power device, a cooling fan that blows air to the cooling structure section 190, and a control unit that forcibly stops operation of the electric power conversion device when a temperature (fin temperature) of the cooling structure section 190 (cooling fin section 194) reaches a predetermined standard (overheat temperature), and estimates an operable time of the electric power conversion device 100 until the temperature of the cooling structure section 190 reaches the predetermined standard.SELECTED DRAWING: Figure 2
