Taking Into Account Interactions between Converters in the Design of Aircraft Power Networks
Résumé
This paper presents some key interactions among
converters, which need to be taken into account when designing a
modern embedded electrical grid, including a large amount of
Power Electronics based loads. A design by Optimization method
is first used to define the converter parameters. During this step,
it is mandatory to account for the interaction between the input
and output EMI filters. The second step consists in designing the
control strategy; the paper will show that the results are largely
improved if all converters are considered simultaneously. Finally,
the stability study of the embedded network has to be
investigated. All these interactions are studied in the example of a
three phases AC network, composed of a Voltage Source Inverter
and an Active Front End.
