Identification of Magnetization Characteristics of Material From Measured Inductance Data.

This paper introduces a novel identification method of the magnetization properties of the core material for an inductor from measured inductance data. The proposed method allows us to obtain the magnetic hysteresis characteristics without a special measurement instrument for material $B - H$ properties. The proposed method determines the parameters included in the distribution function for the Preisach model from the measured $L - I$ characteristics. It is shown that the identified initial magnetization curve and the minor loops are in good agreement with the original $B - H$ curves. The uniqueness for the identification problem is numerically verified. [ABSTRACT FROM AUTHOR]
