Component cost models for multi-objective optimizations of switched-mode power converters

Abstract: Besides product differentiation, cost is a key parameter for market success and sustainable competitive advantage of industrial companies. Academic research in the field of power electronics, however, is often confined to the search for technical innovations or optimizations with focus on pure physical performance indices while the cost dimension is neglected. An explanation for the lack of such cost considerations is the generally poor availability of cost data in academia. This paper discusses the necessity … Show more

“…The selected materials are commonly used in industry and literature and are thus representative candidates for each of the considered fundamental material types: ferrites, tape-wound amorphous iron cores and powder cores. High-performance nanocrystalline materials, such as the Vitroperm500F from Vacuumschmelze, have not been analyzed due their high relative costs [5] and the generally poor availability of cut cores (such as E-cores) as a result of the material's brittleness. Iron powder cores and laminated steel have been neglected for this first analysis due to the comparably high core losses.…”

“…Conunonly known examples are trans formers for galvanic isolation and voltage adaption, AC and DC chokes in switched-mode power converters or differential (DM) and common-mode (CM) inductors for EMI filtering. Typically, the magnetic components do not only use a consid erable share of the total converter volume but also cause high relative costs with respect to other components [1]- [5]. Con sequently, performance optimizations (e.g.…”

“…For the given application also ferrite cores are found to give comparably low power density and efficiency values, which is due to the low saturation flux density of ferrite materials and the relatively low switching frequencies used by reason of the employed semiconductors. Due to the high cost of nanocrystalline materials (23 € /kg) [20] and the comparably small difference in efficiency and power density, the amorphous material (16 € /kg) is selected for realizing the inductors of the converter. Fig.…”

“…The DC-link capacitor is one of the key converter components that affects the cost and the dimension of the whole drive [30]. Furthermore, physical shapes of the capacitors themselves could lead to difficult practical solutions, resulting in a large commutation path for the inverter switches with the related over-voltage problems.…”
