Influence of Parameters Uncertainties in Equivalent Circuit Modeling of 3D Electromagnetic Devices

Abstract

This work deals with the analysis of the effect of parameters' uncertainties in the modeling of electromagnetic devices by equivalent circuits. The sensitivity of the circuit output towards the uncertainty of the circuit parameter variations is defined and a technique for the evaluation of the response bounds in presence of given parameters variation intervals is proposed. Some conclusions on the actual precision and capability of the proposed bound determination technique are evidenced.
