Optimal Design of an AC Filtering Inductor for a 3-Phase PWM Inverter Including Saturation Effect

This paper introduces an optimization method for the design of the filtering inductor of a 3-phase inverter. The inductor model takes into account saturation, copper and iron losses. The optimization method is described, based on a deterministic strategy. Finally, the optimal design of the inductor is given, focusing on the weight minimization and considering a volumetric loss density limitation.
