A Multidisciplinary Design Optimization Approach for EMC Filters Design For More Electric Aircraft Applications

This paper presents an application of Multidisciplinary Design Optimization (MDO) methods to the design of EMC filters applied to aircraft power drive systems. Common-Mode and Differential-Mode filters are traditionally designed separately to simplify the problem. Designing these filters using MDO methods and considering the coupling between them can lead to significant gain on total mass. In the 50kW power drive system designed in this work, a 15 % mass reduction on previous optimal filters was obtained compared to classical methodologies.
