Abstract

The aim of the present paper is to show a simple, but well applicable solution to generate arbitrary waveform of magnetic flux density in scalar hysteresis measurements. The paper deals with a possible realization of eliminating the effect of measurement noise as well. First, the measured signals have been transformed into the frequency domain, and after applying digital filter, the spectrum of the filtered signals have been transformed back to the time domain. The proposed technique results in an accurate noise removal algorithm. The paper illustrates a fast controlling algorithm applying the inverse of the actually measured hysteresis loop, and another proportional one to measure any distorted flux pattern. Developing the mentioned algorithms aims the controlling of a more complicated phenomenon, i.e. measuring the vector hysteresis characteristics.
