Computationally efficient winding loss calculation with multiple windings, arbitrary waveforms, and two-dimensional or three-dimensional field geometry
TL;DR: The squared-field-derivative method for calculating eddy-current (proximity effect) losses in round-wire or litz-wire transformer and inductor windings is derived in this paper.

Cost-constrained selection of strand diameter and number in a litz-wire transformer winding
TL;DR: In this article, the relationship between wire size, normalized cost, and normalized loss is shown to have a general form that applies to a wide range of designs, and a practical design procedure is provided, applied to an example design, it leads to less than half the original loss at lower than the original cost, or, alternatively, under one fifth the original costs with the same loss as the original design.

Experimental determination of stray capacitances in high frequency transformers
TL;DR: In this paper, the two-port network approach and the step-response approach are used for determining stray capacitances in a two-winding high frequency transformer for circuit simulation and computeraided design purposes.
Journal ArticleDOI
Measurements and performance factor comparisons of magnetic materials at high frequency
TL;DR: In this paper, the design of power magnetic components for operation at high frequency (HF, 3-30 MHz) has been hindered by a lack of magnetic material performance data and by the limited design theory in that frequency range.
Proceedings ArticleDOI
Core losses under DC bias condition based on Steinmetz parameters
TL;DR: In this paper, the Steinmetz premagnetization graph (SPG) is introduced to calculate core losses under DC bias conditions, and a detailed description of the test system is given, as high accuracy is crucial.

Optimum electromagnetic design for wound components in SMPS applications
TL;DR: A design programme has been developed to optimise the conductor design with distributed airgap geometry and it was found that both the components of fringe field and cross component of leakage field reduce with the increasing number of airgaps.

Evolution of Magnetic Properties in Ferrites: Trends of Single- Sample and Multi-Sample Sintering
TL;DR: In this article, the results of single-sample and multi-sample sintering of NiZn ferrites and yttrium iron garnet (YIG) were highlighted, and their microstructural consequences on the magnetic properties were also discussed.
Capillary waveguide improvements for laser plasma accelerators
TL;DR: The required complexity or quality of research of student theses may vary by program, and the required minimum minimum study period may vary in duration as discussed by the authors. But the grade received is not published on the document as presented in the repository.
