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.

International audience; The paper deals with the frequency modelling of EMC phenomena using equivalent circuit (with frequency perturbation sources for the modelling of the switching cells of the static converters) in the context of the sizing by optimization of EMC filters. The paper focusses on the way to obtained automatically a frequency model, including the exact computation of its jacobian, useful in the context of design by deterministic gradient optimization. It mainly focuses on selectivity (optimization contextualization) in the modelling with its interests compared to a generic modelling (without knowing with variables will be constrained in the optimization process). The approach is applied to the optimization of EMC filter for power electronics aircraft context.

International audience; This paper presents some key interactions amongconverters, which need to be taken into account when designing amodern embedded electrical grid, including a large amount ofPower Electronics based loads. A design by Optimization methodis first used to define the converter parameters. During this step,it is mandatory to account for the interaction between the inputand output EMI filters. The second step consists in designing thecontrol strategy; the paper will show that the results are largelyimproved if all converters are considered simultaneously. Finally,the stability study of the embedded network has to beinvestigated. All these interactions are studied in the example of athree phases AC network, composed of a Voltage Source Inverterand an Active Front End.

International audience; As aircraft installed electrical power continues to increase, maintaining the advantages of MEA approach highly relies on the ability to design low-weight on-board electrical network and power electronic conversion systems. However, design and integration of the power system still follow the legacy standards, where locally optimized individual components may not result in optimum system. This paper presents an attempt at exploring the advantages and barriers to integrated design where subsystem interactions are accounted for and the power system is optimized as a whole. As an example, the weight of a notional subsystem of the MEA electrical power system – consisting of a dc bus, a rectifier, an ECS, and an EMA – is studied and optimized as a function of the dc bus voltage, while taking into account the power quality, EMI, and stability constraints. Although the example follows a traditional (decoupled) design approach, the individual component modeling and design processes are formalized with similar structures, so that future system-level integrated design by optimization can be evaluated.

Purpose – Multiphysical models are often useful for the design of electrical devices such as electrical machines. In this way, the modelling of thermal, magnetic and electrical phenomena by using an equivalent circuit approach is often used in sizing problems. The coupling of such models with other models is difficult to take into account, partly because it adds complexity to the process. The purpose of this paper is to propose an automatic modelling of thermal and magnetic aspects from an equivalent circuit approach, with its computation of gradients, using selectivity on the variables. Then, it discusses the coupling of various physical models, for the sizing by optimization algorithms. Sensibility analyses are discussed and the multiphysical approach is applied on a permanent magnet synchronous machine. Design/methodology/approach – The paper allows one to describe thermal and magnetic models by equivalent circuits. Magnetic aspects are represented by reluctance networks and thermal aspects by thermal equivalent circuits. From circuit modelling and analytical equations, models are generated, coupled and translated into computational codes (Java, C), including the computation of their Jacobians. To do so, model generators are used: CADES, Reluctool, Thermotool. The paper illustrates the modelling and automatic programming aspects with Thermotool. The generated codes are directly available for optimization algorithms. Then, the formulation of the coupling with other models is studied in the case of a multiphysical sizing by optimization of the Toyota PRIUS electrical motor. Findings – A main specificity of the approach is the ability to easily deal with the selectivity of the inputs and outputs of the generated model according to the problem specifications, thus reducing drastically the size of the Jacobian matrix and the computational complexity. Another specificity is the coupling of the models using analytical equations, possibly implicit equations. Research limitations/implications – At the present time, the multiphysical modelling is considered only for static phenomena. However, this limit is not important for numerous sizing applications. Originality/value – The analytical approach with the selectivity gives fast models, well adapted for optimization. The use of model generators allows robust programming of the models and their Jacobians. The automatic calculation of the gradients allows the use of determinist algorithms, such as sequential quadratic programming, well adapted to deal with numerous constraints. [ABSTRACT FROM AUTHOR]
