Abstract

The implementation of a new equipment onboard an electrical DC network, requires stability conditions, concerning the sole equipment associated with its input filter as well as the whole system, to be fulfilled. In this scope, several modeling approaches of the loads in the frequency domain are considered: analytical model of the load´s input admittance and experimentally measured or simulated Bode diagrams of this admittance. The merit of each of these models with respects to stability criteria (Routh-Hurwitz and Middlebrook criteria are considered) is analyzed and its usability for the help in dimensioning the input filter is studied.
