Analytical modeling of static converters for optimal sizing of on-board electrical systems

Power electronics converters can generate a high level of harmonic perturbations on on-board electrical systems (planes, ships, road vehicles...). For the optimal sizing of these systems, harmonics must be known to select the best components (generator, filter...) that will limit their effects. In the paper, an analytical frequency domain modeling is proposed to accurately compute the harmonics generated the static converters. Because no numerical simulation is used, the presented approach is fast, accurate and applicable for optimal sizing or sensibility analysis. It is also valid for every kind of static converters. It is illustrated by its application to the sizing of an AC/DC power converter used for connecting electrical generators to DC on-board networks.
