“…Large gaps, however, produce magnetic 'fringing' causing eddy current losses in adjacent conductors, significantly impacting converter efficiency. This extra power loss can be observed in the form of 'hot spots' [5][6][7][8].…”

“…While combining two materials to form a core without an air gap, both should have a usable flux density Buse in the same range. KoolMµ (Sendust) material has a soft saturation curve with a B sat in the range of around 1 T. The preferred range of magnetic induction in amorphous and nanocrystalline cores is also, due to core loss effects, in the range up to 1 T [4,7,[15][16][17][18].…”

PFC Inductor Design Considering Suppression of the Negative Effects of Fringing Flux

et al. 2022

In this paper, the main aim of the study was the investigation of the possibilities of power inductor design, reflecting the performance of the component itself, as well as the operational efficiency of the power factor correction (PFC) converter. PFC inductors represent a key component of the converter, while within the design of any magnetic component, several design rules must be considered to provide proper operational performance. Here we discuss skin-effect, while the proximity effect and formation of fringing flux pose a more serious problem in terms of mitigating their negative impact. Therefore, in this study, the space is devoted exclusively to the analysis of the impact of the fringing flux of the PFC inductor and subsequently to the possibilities of its suppression. The resulting optimizations are reflected in the investigation of the operational efficiency of the PFC converter.
