Influence of the Geometric Uncertainties on the RLC Parameters of Wound Inductors Modeled Using the Finite-Element Method

In this paper, we highlight the influence of geometrical uncertainties (winding pattern and wire diameter) on the RLC parameters of wound magnetic components. To that end, the finite-element method is embedded in a Monte Carlo simulation in order to compute probability distributions of the parameters. An algorithm to randomly generate realistic winding configurations is also proposed.
