“…The transient thermal characteristic can be determined using application software and a tester [9], which is designed to control the electrical parameters o f high-frequency switching voltage converters (HFSVC) under mass production conditions. As a result of the UF(t) experiment, an array of digits is obtained, which should be converted into an array of digits T∑(t) and t hen T(t), где T(t)=T∑(t)−Tα, T is the heating temperature of the HFSVC crystal; T∑ is the total HFSVC crystal temperature; Tα is the ambient temperature.…”

“…Therefore, the practice of applying complex multidisciplinary models is expanding. Usually, finite element models with distributed parameters [1][2][3][4][5] or with lumped parameters [6][7][8][9] are used. The first type of models allows modeling, taking into account many design features, but it requires a larger amount of input data for model compilation as well as a high level of scientific competence of the developer, which is not often observed in engineering practice.…”

In the current study, it was tried to describe a method for determining thermal characteristics of integrated micro-circuits to identify thermal parameters of multidisciplinary (thermal-electric) behavioral models. The problem is solved on the example of high-frequency pulse voltage converters. A solution was proposed to refine the minimum structure of the thermoelectric model based on an iterative least squares method using the Levenberg-Marquardt algorithm, as well as a graph of the spectral den-sity of time constants. This made it possible to reduce the influence of the filtering factor in the deconvolution operation when building a thermal model using the structural function of the thermal characteristic transition. Also, the results obtained can be used to build integrated circuits (IC) behavioral models, taking into account the thermal processes occurring in them.
