EFFECT OF EXCITING FIELD WAVEFORM ATTRIBUTES ON QUASI-STATIC HYSTERESIS LOOPS

Elemír Ušák

   This paper is focused on the investigation of various exciting field as well as the flux density waveform attributes, such as the frequency, amplitude and especially the shape on the resulting hysteresis loops and associated magnetic parameters. The experiments have shown significant difference between two major cases – continuous and discontinuous waveform; moreover even in the case of continuous waveforms there are substantial differences between various magnetic parameters (ie complex power losses, complex permeability) evaluated from the measured waveforms resulting in the same hysteresis loop shape.

Keywords: hysteresis loop, magnetic parameters, power losses, complex permeability, relaxation effects
