Dynamic B-H Curves of Magnetic Materials Under Magnetic Switching Transients
Abstract
The characteristics of a ferrite core saturating inductor under capacitive discharge were investigated both theoretically, with the use of computer modeling techniques on a HP-85 microcomputer, and experimentally on an actual ferrite core inductor. To correlate the modeling technique with experiment, the voltage across and the current through the ferrite core inductor under capacitive discharge excitation were measured. Since the magnetic flux density and field strength can be determined from these measurements, a dynamic trajectory of the magnetic flux density as a function of the magnetic field strength for the ferrite core was made. The data from this "dynamic B-H curve" was fed into an HP-85 microcomputer and the model generated hysteresis energy and power plots as a function of time. These p"lots agreed well with the measured data except for a small discontinuity in the theoretical plots due to the piece-wise linear approximation used in modeling.
