- Abstract:
- The sensorless determination of the dynamic hysteresis loop of the magnetic materials, and in particular those of magnetic plates, can be obtained under ac symmetric conditions in a relatively simple way. This paper proposes a new digital method and instrument for the sensorless determination of the dynamic hysteresis loop under ac asymmetric conditions, in the presence of a dc flux polarization. The method is based on the determination of the parameters of a simplified linear circuital model of the magnetic circuit, which shows an energy equivalence. The results of some experimental work are provided in order to validate the proposed method.
