Comparison of smoothing methods for the analysis of transient thermal resistance

In this paper, the analysis of transient thermal resistance is carried out on the basis of the regularization smoothing method and the Fourier series expansion method. These two methods are used to smooth cooling curve under the hypothetical model, and their result of smoothing and derivation are contrasted to the move average smoothing method under the actual model measured by T3ster. From theoretical model analysis and actual measured data analysis and application, it can be seen that the methods proposed have good effect on the analysis of transient thermal resistance.
