Abstract
This paper describes possible procedures for
computation of static self-inductances and static mutual
inductances in nonlinear magnetic systems. The procedures are
based on numerical calculation of magnetic field with finite
element method. Previously mentioned calculations are carried
out for various current excitations. Inductances are calculated
with magnetic flux of coils and with magnetic field energy.
Single-phase transformer is used as a test model for
verification of inductance calculation procedures. Calculated
results of inductance values, magnetic fluxes and magnetic field
energy are estimated in regards to the measurements of the
geometrically and physically identical realistic transformer.
