1. Introduction
The concept of More Electrical Aircraft consists in improving the energetic efficiency of aeronautic systems by increasing the electrical embedded vectors. It is now one of the key drivers of technological developments in aerospace. Power converters represent a significant part of the new technologies, and their power density still needs to be improved in order to save weight and therefore fuel consumption. Design automation using optimization method is an interesting way to reach this goal, defining the converter weight as the objective function, and considering the numerous aeronautical constraints. Sequential approach in the design may result in sub-optimal results, because several compromises are necessary during the choice of some parameters [1]. For example, the switching frequency has an opposite impact on the sizing of the semi-conductors and on the design of a low-frequency filter. Solving all tradeoffs simultaneously is the role of the optimization tool.
