Abstract

The electrical power within electronic components is connected with large quantity heat discharge which has to be removed in order to avoid risk of failure due to overheating. This paper presents an analysis of infrared camera implementation for correct temperature field estimation. This is necessary regarding the temperature measurement specifics with regard to power electronic elements during different regimes of exploitation. An infrared thermal camera Flir i7 has been used. Test measurements are performed and the influence of main measurement parameters over the thermal radiation of the bodies is discussed. Regression equation for temperature correction is calculated.
