Abstract

The use of 3D thermal simulations of magnetic components for power converters is limited to validation of final designs due to time consumption. A two-step homogenization is proposed to simplify them, while keeping good accuracy. The required equations and some guidelines are described in this paper to apply it to solid round wire, litz wire or foil wound magnetic components. Considerations to extend its use to transformers, including the use of interleaving techniques and insulating tape are explained. This method can reduce the running time of 3D simulations (seven times faster than usual simulations) while the convergence is assured even for complex structures or cases with litz wire. Finally, the proposed method is experimentally validated with DC and AC excitation.

Bibliometric impact. Analysis of the contribution and dissemination channel

The work has been published in the journal IEEE TRANSACTIONS ON POWER ELECTRONICS due to its progression and the good impact it has achieved in recent years, according to the agency WoS (JCR), it has become a reference in its field. In the year of publication of the work, 2020, it was in position 31/273, thus managing to position itself as a Q1 (Primer Cuartil), in the category Engineering, Electrical & Electronic.

From a relative perspective, and based on the normalized impact indicator calculated from World Citations provided by WoS (ESI, Clarivate), it yields a value for the citation normalization relative to the expected citation rate of: 1.69. This indicates that, compared to works in the same discipline and in the same year of publication, it ranks as a work cited above average. (source consulted: ESI Nov 13, 2025)

This information is reinforced by other indicators of the same type, which, although dynamic over time and dependent on the set of average global citations at the time of their calculation, consistently position the work at some point among the top 50% most cited in its field:

  • Weighted Average of Normalized Impact by the Scopus agency: 2.14 (source consulted: FECYT Mar 2025)

Specifically, and according to different indexing agencies, this work has accumulated citations as of 2026-04-26, the following number of citations:

  • WoS: 31
  • Scopus: 45
  • Open Alex: 39

Impact and social visibility

From the perspective of influence or social adoption, and based on metrics associated with mentions and interactions provided by agencies specializing in calculating the so-called "Alternative or Social Metrics," we can highlight as of 2026-04-26:

  • The use of this contribution in bookmarks, code forks, additions to favorite lists for recurrent reading, as well as general views, indicates that someone is using the publication as a basis for their current work. This may be a notable indicator of future more formal and academic citations. This claim is supported by the result of the "Capture" indicator, which yields a total of: 19 (PlumX).

It is essential to present evidence supporting full alignment with institutional principles and guidelines on Open Science and the Conservation and Dissemination of Intellectual Heritage. A clear example of this is:

  • Assignment of a Handle/URN as an identifier within the deposit in the Institutional Repository: https://oa.upm.es/94038/

As a result of the publication of the work in the institutional repository, statistical usage data has been obtained that reflects its impact. In terms of dissemination, we can state that, as of

  • Views: 34
  • Downloads: 9
Continuing with the social impact of the work, it is important to emphasize that, due to its content, it can be assigned to the area of interest of ODS 7 - Affordable and clean energy, with a probability of 85% according to the mBERT algorithm developed by Aurora University.

Project objectives

Los objetivos perseguidos en esta aportación se centran en mejorar la modelización térmica de componentes magnéticos mediante simulaciones 3D. Se pretende, en primer lugar, analizar y simplificar las simulaciones térmicas mediante una homogenización en dos pasos que mantenga la precisión. Además, se busca describir las ecuaciones necesarias y proporcionar directrices para su aplicación en componentes magnéticos con alambre sólido, alambre litz o bobinado en lámina. Otro objetivo es evaluar la extensión del método a transformadores, considerando técnicas de intercalado y cinta aislante. Finalmente, se pretende validar experimentalmente la metodología propuesta bajo excitación continua y alterna, logrando una reducción del tiempo de simulación siete veces superior a los métodos habituales.
