Improvements of Preisach model for soft magnetic materials, analysis of input excitation signal

Popis výsledku v původním jazyce

Determination of the weighting function of the Preisach hysteresis model depends strongly on the quality of experimental data. The paper focuses on errors in the input exciting current. The analysis of experimental data and their processing were identified main source of errors: RF noise, quantization jumps at signal synthesis, power net interference and short term faults of used power supply. Their reduction is possible by insertion of filter in between the power source and measured sample. The filter was designed with respect to main frequencies of both the useful and disturbing signal. Its simulations are validated with measurements and the improvement of measured waveforms in time domain is demonstrated.
