VI-CHARACTERIZATION OF SOFT MAGNETIC MATERIALS BY DRIVING CURRENT OR VOLTAGE
Romano Giannetti, Mirko Marracci, Bernardo Tellini, Carmine Zappacosta
Abstract:
We analyse the volt-amperometric (VI-) method for the characterization of minor loops of soft magnetic materials. By adopting several input signals and by operating at various frequencies in the 10 Hz – 10 kHz frequency range, we perform the measurement on a soft ferrite core. Through the use of two different measurement schemes, we control in the first case the voltage across– and in the second case the current through– the primary coil. Measurement results are reported and a comparison among the various techniques is provided throughout the paper. A commercial ferrite core and a Fe-Si thin lamination are used as our samples.
