   A New Concept to Design Inductors with Low Conducted and Radiated Emission Noises
By Firuz ZARE [View]
[Download]

Abstract: This paper presents a new configuration of inductor utilized in modern power electronics systems with high switching frequency. The main advantage of the proposed inductor is to suppress high frequency conducted and radiated emission noises. Several high frequency analysis and measurement have been carried out to verify the proposed concept.

   Frequency-Domain Homogenization for Litz-Wire Bundles in Finite Element Calculations
By Korawich NIYOMSATIAN [View]
[Download]

Abstract: This work deals with a frequency-domain homogenization method for litz-wire bundles embedded in a finite element (FE) model. The approach consists in adopting a frequency-dependent complex reluctivity in the litz-wire bundles and a frequency-dependent complex impedance in the electrical circuit in terms of dimensionless coefficients. The litz-wire bundles become homogeneous conductors which are easy to integrate into a finite element model. The homogenization methods in previous works are also reviewed. The complex permeability achieved with our model is compared to the most accurate expression found in literature. The agreement is very good despite the different elementary cell and condition setting. Moreover, the homogenization method in this paper is validated for both 2-D and 3-D FE calculations with the translational-symmetry transformer model and the axisymmetric inductor model respectively. The reference solutions of those models are computed by finely discretizing each conductor inside the litz-wire bundle. The results of the computed resistance and inductance agree well with those computed by the reference fine model, resulting in less than 3\% and 0.05\% maximum errors respectively in 2-D FE model, and 4\% and 1.8\% respectively in 3-D FE model with several times less computational cost.

   The Reluctance of Large Air Gaps in Ferrite Cores
By Erika STENGLEIN [View]
[Download]

Abstract: Air gap reluctance and the effective cross-sectional area strongly depend on size, shape and position of the air gap. This paper introduces a novel approach to quickly predict the effective cross-sectional area as a function of these influencing factors. Special attention is paid to the reluctance of large air gaps.
