Egiziano, Patrizia Lamberti, and Vincenzo Tucci doi:10.2529/PIERS070220045559 Downloads: 848 Abstract:This paper presents an effective and reliable tool for evaluating inductance co-efficients in presence of uncertain parameters in a simple and compact form. The inductance coefficients in some interesting applications are obtained by applying the Interval Arithmetic to the Hopkinson's law. The proposed approach allows to efficiently take into account the presence of the geometric tolerances and the non linearity of the ferromagnetic materials. It is shown that the resultant intervals include the actual values of the coefficients thus improving the reliability of the components design.References:1. Erickson, R. W. and D.
