Sažetak
If the mathematical description of the magnetic hysteresis loop branches should be simple, easy to use and should credibly describe the waveform magnetic hysteresis loop with a minimum number of parameters, then it inevitably leads to the description of magnetic hysteresis loop branches with a hyperbolic tangent function. This paper presents the advantages in description of magnetic hysteresis loop branches with a hyperbolic tangent function over other functions. The advantages in description of magnetic hysteresis loop branches with dual hyperbolic tangent function versus description with a single hyperbolic tangent function when the magnetic hysteresis loop has a very pronounced saturation region are provided. Also, this paper presents numerical difficulties in describing of magnetic hysteresis loop branches with a hyperbolic tangent function. Using soft magnetic material, as an example, a numerical procedure for determining parameters in description of magnetic hysteresis loop branches with a single and two hyperbolic tangent functions is shown. The numerical results are analyzed and discussed.
