“…FEM is a big world, as it was explained in the section before. Once the magnetic component’s design is complete (windings and core parameters) and validated in FEM; the next step consists in exporting the final FEM design to software like Simulink ® or Twin Builder ® , PSIM ® , to simulate it in a specific application and corroborate its correct performance [ 59 , 143 , 144 , 145 , 146 ].…”

In power electronics, magnetic components are fundamental, and, unfortunately, represent one of the greatest challenges for designers because they are some of the components that lead the opposition to miniaturization and the main source of losses (both electrical and thermal). The use of ferromagnetic materials as substitutes for ferrite, in the core of magnetic components, has been proposed as a solution to this problem, and with them, a new perspective and methodology in the calculation of power losses open the way to new design proposals and challenges to overcome. Achieving a core losses model that combines all the parameters (electric, magnetic, thermal) needed in power electronic applications is a challenge. The main objective of this work is to position the reader in state-of-the-art for core losses models. This last provides, in one source, tools and techniques to develop magnetic solutions towards miniaturization applications. Details about new proposals, materials used, design steps, software tools, and miniaturization examples are provided.

“…Os autores consideram núcleos de aço silício, amorfo e pó de ferro. No entanto, diferentemente de [16], [17], a análise do material não está relacionada aos graus de liberdade para determinação de L e C, ao passo que indutores com diferentes tecnologias terão desempenhos diferentes de acordo com seu conteúdo harmônico [23].…”

This work presents a methodology for designing LC filters, analyzing their impact on the converter. It takes into account the losses and the volume of the filter, the losses and the volume of the converter, and the useful life of the capacitors. The methodology is based on the execution of physical dimensioning (part numbers, volume) and estimation of losses in each part of the system, employing experimentally validated analytical models. From a mission profile and capacitor losses, the lifetime is estimated for the capacitors of the LC filters and the DC bus. The design is optimized in terms of losses in the system, total volume, and lifetime of the capacitors. The benefits of prioritizing each of these attributes indicated.

“…Para a estimativa das perdas e volume dos indutores do filtro LCL, o projeto físico iterativo é executado considerando diversas tecnologias para L g e L c . Para materiais magnéticos, são considerados núcleos de ferro silício de grão não-orientado (Fe-Si GNO) [21], por seu baixo custo; núcleos Kool Mµ [22], por sua alta densidade de fluxo suportada e custo relativo baixo comparado à outras tecnologias de material de pó de ferro [23]; e núcleos de ferrite 3C92 [24] por suas baixas perdas magnéticas. Todos os núcleos são de geometria EI ou EE, e seu empilhamento é considerado.…”

This work presents a methodology for LCL filter design applied to grid connected converters. It is based on the combined analysis of the parametric and physic design. Different combinations of L-C-L that meet normative restrictions are determined, in order to find the values that result in the smallest total volume, highest capacitor lifetime, or a compromise among both. For this, component losses are modeled, as well as practical aspects and particularities of each technology employed in the filter. Electrical and thermal experimental results validate the proposed methodology.
