Abstract :
We propose in this paper a mathematical modeling and a numerical simulation of a nonlinear magnetic circuit. The resolution of the differential equation describing the model of the iron core is carried out while taking as a starting point the Lomonosoff method. It consists in finding a periodic solution of the problem and whose function is given by a Lagrange polynomial approximation, while introducing the nonlinearity resulting from the relation B(H) intrinsic to the used material.
