SPICE model for effective and accurate time domain simulation of power transformers

Impact of a Punching Process on the SyRM Iron Loss: SPICE Model as an Effective Tool for Iron Loss Modeling

“…where γ s is the degradation factor (suggested as equals to 0), and δ s is the degradation skin depth. Then, the B flux density profile can be directly linked to the degradation profile, and hysteresis loss can be expressed as [24] P h (x) = P hnd / γ(x) (9) where P hnd is the hysteresis loss for undamaged material, and γ(x) is the degradation profile described by (8).…”

“…For commonly used professional tools, we include, for example, MATLAB, often used in cooperation with Simulink, Mathematica, SPICE, Octave, Scilab, and other software. In this group, we can indicate the software such as MATLAB or Simulink intended for modeling physical phenomena and signals belonging to a broad research area [7][8][9][10][11] and SPICE dedicated to modeling and analyzing mainly electronic circuits. However, the literature provides many examples of much more expansive use of this tool, which exceeds far beyond electronics [12][13][14][15][16][17].…”

Multi-objective design of a close-coupled inductor for a three-phase interleaved 140kW DC-DC converter

“…To this end, a reluctance model of the magnetic core is made [4] [5]. Saturation is modeled by approximating it with the Langevin function [6]. Hysteresis and eddy-current effects are not modeled as the hysteresis surface of ferrite is small and the electric resistivity is high.…”

“…Conductive thermal resistances can be calculated using (6), where l is the length of the conductive path, A is the crosssectional area and k is the thermal conductivity of the material. The latter is given for different materials in table 3.…”
