EN In the article, the influence of the frequency of the power source on the value of the input impedance of higher frequency transformer (HF) in various operating states has been investigated. The relationship of the input impedance of the considered transformer has been determined using the equivalent circuit model based on the equations of 2D field-circuit model and Cauer circuits. For this purpose, the authors have elaborated a field circuit model of the HF transformer, the equations of which, i.e. the equations of the finite element method (FE equations), through the transformation using Proper Orthogonal Decomposition (POD) method and the Singular-Value Decomposition (SVD) method, will allow obtaining the parameters of the equivalent model for the system. The obtained results of the impedance characteristic have been compared with the results obtained on the basis of the full field model.
