DESIGN BY OPTIMIZATION OF A THREE PHASES AFE UNDER EMCCONSTRAINTS

International audience; This paper compares a step by step design of a power electronicsconverter with the results obtained using a design by optimization technique, solvingall equations together. “Order one” method is privileged, in order to facilitateseeking a design optimum in a very constrained space of solutions (especially due toElectromagnetic Compatibility). Specific derivable models for each constraint andcomponent design have been used. Difficulties of these derivable formulations areunderlined, as well as the effectiveness of the method in comparison with theconventional step by step approach, especially regarding EMC.
