Practical Wide Frequency Approach for Calculating Eddy Current Losses in Transformer Windings

Abstract: The proposed method is verified by designing several transformers. As an example, a 2.5 kW transformer is fully described. The experiments show good matching with the calculations.

“…The accuracy of determining the losses in the coils of a transformer is important for evaluating its performance. Works [66,68,69] are devoted to this issue. In [68], the authors use a three-dimensional statement of the transformer model based on the finite element method to calculate eddy currents and losses in the transformer winding.…”

“…The effect of uneven distribution of electrical losses can be taken into account only in spatially distributed models. In [69], the authors propose to introduce a correction factor k c to calculate the electrical losses in the transformer coils P = RI 2 k c . This coefficient makes it possible to take into account the influence of proximity effects and the skin effect, depending on the main power frequency and the size of the winding turns.…”

“…A. Van den Bossche et al [34] reports a practical method for calculating eddy current losses which attempt to improve the classical loss calculation by instituting a loss factor. A graphical approximation of the loss coefficient as a function of wire diameter, frequency, layer number and copper packaging factors are attained by comparing the analytical approach with FEM simulations and substantiated by designing various transformers.…”

“…Se han publicado diversos métodos para medir o calcular ∆P EC1 [61]- [63]. De acuerdo con [63] ∆P EC1 puede ser calculado fácilmente en función de la pérdida de potencia en el cobre provocada por la corriente rms fundamental de cada fase en el devanado secundario del transformador, obteniéndose mediante la siguiente expresión:…”
