DESIGN BY OPTIMIZATION OF A THREE PHASES AFE UNDER EMC CONSTRAINTS
Résumé
This paper compares a step by step design of a power electronics
converter with the results obtained using a design by optimization technique, solving
all equations together. “Order one” method is privileged, in order to facilitate
seeking a design optimum in a very constrained space of solutions (especially due to
Electromagnetic Compatibility). Specific derivable models for each constraint and
component design have been used. Difficulties of these derivable formulations are
underlined, as well as the effectiveness of the method in comparison with the
conventional step by step approach, especially regarding EMC.
