The infrared thermography today is widely used modern instrument for analysis of thermal fields in power electronics elements. On the other side, the heat fluxes causing temperature distribution of these elements and modules in working condition can be estimated in regimes of exploitation, while the cooling may be optimized in order to avoid damages of overheating. In present work, an algorithm and computer application for calculation temperature gradient on the surface of analyzed objects based on infrared thermal images is presented.


Keywords –infrared thermography, raster to vector conversion, heat dissipation, electronic elements.
