Abstract

Razvili smo sustav za mjerenje temperature i napona dvaju strujnih pretvornika. Jedan strujni pretvornik je smješten u kontroliranim uvjetima stalne temperature, dok je drugi podložan promjenama temperature. Praćenje temperature i napona omogućilo nam je prikupljanje podataka pomoću kojih smo izrašunali toplinske vremenske stalnice koju smo kasnije interpolirali kako bismo predvidjeli toplinske vremenske stalnice za određene temperature. Osim toga, razvili smo grafičko korisničko sučelje koje omogućuje ispravljanje pogrešaka i predviđanje toplinske vremenske stalnice. Ovaj alat olakšava analizu i upravljanje mjerenjima te doprinosi točnijem razumijevanju ponašanja strujnih pretvornika pod različitim temperaturnim uvjetima.

Abstract (english)

We have developed a system for measuring the temperature and voltage of two current converters. One current converter is housed in controlled conditions of constant temperature, while the other is subject to temperature changes. Temperature and voltage monitoring allowed us to collect data that we used to calculate thermal coefficient of resistance, which we later interpolated to predict thermal coefficient of resistance for specific temperatures. In addition, we have developed a graphical user interface that allows for error correction and prediction of thermal coefficient of resistance. This tool facilitates the analysis and management of measurements and contributes to a more accurate understanding of the behavior of current converters under different temperature conditions.
