Determination of Core Losses Using an Inverse Modeling Technique

This paper presents an inverse thermal modeling technique to determine the core losses from temperature rise inside transformer core. For this purpose, initially, a customized printed circuit board (PCB) with sensors is used measure rise. Afterward, 3D magneto-thermal forward model developed validate The accuracy of checked by comparing simulated and experimental measurements for different supply conditions. results show that can accurately estimate maximum relative error less than 2.7% predict in 6.2%. Lastly, after ensuring model, applied directly measured estimating measurements. novel approach PCB design besides shows be compared experiments.
