High-frequency and high-power density converters are essential for many applications such as automotive and more electric aircraft. To improve power density, planar magnetic components are increasingly used in power electronic converters owing to their advantages, such as less high-frequency losses, repeatability, and better thermal performance compared to conventional wound components. Considerable attention has been paid to their electrical performance. However, the thermal aspects are essential for enhancing completely their performance. Currently, there is an increasing interest in these critical aspects of high-density power converters. This paper presents a literature review of studies on the thermal modeling of planar magnetics. The papers were organized according to the model type and analyzed to highlight their merits and limitations. A multicriteria comparison of the studied papers was performed. Moreover, the key points and issues related to the thermal modeling are addressed to guide designers in enhancing the thermal aspects of planar magnetic components.INDEX TERMS Planar magnetics, High frequency magnetics, Thermal modeling, high power density.

“…Nevertheless, some research regarding the impact of forced convection in the converter power density can be found in [95]. Further details regarding advanced thermal management techniques were analyzed in [92] for planar transformers for space applications. Nevertheless, the same conclusions can be stated for conventional magnetics and other industrial environments.…”
