DESIGN BY OPTIMIZATION OF A THREE PHASES AFE UNDER EMCCONSTRAINTS

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.
