“…Filament models are commonly used to calculate the resistance and inductance of a conductor. The VuDinh model [7] is easily programmed and can quickly solve for the skin-effect in a rectangular conductor-cross section. Referring to Fig.…”

“…The corner frequency can be defined as the frequency where the skin-depth is half of the conductor thickness, which can be computed with Eq. 4 [7], and is more difficult to model because the resistance transitions from its DC behavior to a high-frequency behavior. Returning to Fig.…”

“…The mutualinductances shut off the current flow in the center conductors as the frequency increases, leaving only outside layers for the current to flow. A ladder circuit can be calculated to determine the impedance at a given frequency [7][8][9][10][11][12]. A major limitation of the current skin-effect models is that they have not yet been extended to model the skin-and proximity-effect resistance and inductance of transmission lines with various non-rectangular cross-sections.…”

Predictability of transmission line parameters in both the frequency and time-domains is very important for microelectronics packaging. Proximity effects and non-rectangular cross-sections can cause a drastic deviation in transmission line parameters from the theoretically calculated values. Filament models and full-wave techniques have offered improvements over analytical models for computing the parameters of transmission lines with arbitrary cross-sections including proximity effects. This work is an analysis of some state-of-the-art skin-effect models and a quantification of their limitations

“…Boosted by the availability of increasingly powerful circuit simulators, the modeling of electromagnetic structures using equivalentcircuit approaches is a current topic of interest, in particular, when dealing with skin effect problems [3][4][5][6][7][8]. One novelty with this work, which also deals with problems related to skin effect [9,10], resides in the consideration of inhomogeneous materials, which can display predominant conducting properties, insulation properties, magnetic properties, or a mix of all.…”

Abstract-An equivalent circuit, made of the chain connection of a number of T-type two-port networks, is proposed for the very accurate representation of the frequency-domain behavior of radially inhomogeneous solitary cylindrical structures, the individual two-port networks being made of frequency-independent R, L and C lumped elements. The accuracy of the model is dictated by the number of two-port networks, a number that increases with the frequency. The equivalent circuit approach is validated with the help of an application example concerning a special type of inhomogeneous tubular structures where exact closed-form field solutions do exist.

Fuses may in the future enter into the DC-link of voltage source converters and the harmonic power losses prediction in fuses are very important for the manufacturers in order to predict life-time and protection level of the converter.The DC-link current has a high harmonic content for an inverter that uses any kind of Space Vector Modulation strategy. The aim of this paper is to find a useful approximation for the AC resistance of a fuse and to predict the harmonic power losses into it when it is fed from an inverter.I.
