Method for current/voltage post-correction for efficient hysteretic magnetic field analysis

摘要

Two post-processing methods of correcting the current-voltage property are proposed for the efficient hysteretic magnetic field analysis. One uses the instantaneous power difference by the post-processing method. The other gives an equivalent resistance to the hysteresis effect. The analysis of the drum-type ferrite-core inductor using the former method agrees with the finite element magnetic field analysis that directly handles the hysteretic property.
