Taking Into Account Of The Non-Linearities Of The Magnetic Material For The Characterization In Steady State Under Presumed Sinusoidal Voltage Of The Behavior Of A Single-Phase Magnetic Circuit

Jean-Francois Brudny

Résumé

The developments presented consider, via r, the non-linearities of the magnetic material to determine, based on the conventional equivalent scheme, the equations which characterize the operation in steady state of a singlephase Magnetic Circuit (MC) supplied with a presumed sinusoidal voltage. If some results have already been the subject of a scientific publication, this new article is characterized by the numerous experimental exploitations. These validate all the specific equations applicable whether or not the MC is affected by saturation. On the other hand, the exploitation of these equations makes it possible to access practical information concerning this MC which is difficult to obtain by other methods. The original aspects resulting from this analysis are at several levels. - Establishment, on the basis of a semi-analytical method of investigation already exposed, of the complete system of equations governing the behavior of the MC. - Presentation of a simple and fast procedure for the characterization of the impedance of the grid which supplies this MC. - Identification of the iron loss analytical model and quantification of the associated variable resistive elements. - Extension to the determinations of the experimental anhysteretic and r(b) characteristics of the magnetic material. - Analysis of the impacts of these specific formulations on the fundamental iron losses determined using dedicated devices such as Epstein frame.
