Improved Formulae for the Inductance of Straight Wires

open access: yesAdvanced Electromagnetics, 2014
The best analytical formulae for the self-inductance of rectangular coils of circular cross section available in the literature were derived from formulae for the partial inductance of straight wires, which, in turn, are based on the well-known formula ...

One Hundred and Fifty Years of Skin Effect

open access: yesApplied Sciences, 2023
In 1873, J.C. Maxwell derived relations for current density and current in a solitary long cylindrical conductor supplied with variable current. According to Maxwell, the current density in a conductor increases towards the conductor surface.

Self inductance of a wire loop as a curve integral

open access: yesAdvanced Electromagnetics, 2016
It is shown that the self inductance of a wire loop can be written as a curve integral akin to the Neumann formula for the mutual inductance of two wire loops. The only difference is that contributions where the two integration variables get too close to

On Simplified Calculations of Leakage Inductances of Power Transformers

open access: yesEnergies, 2020
This paper deals with the problem of the leakage inductance calculations in power transformers. Commonly, the leakage flux in the air zone is represented by short-circuit inductance, which determines the short-circuit voltage, which is a very important ...

Closed Form Expressions of Self and Mutual Inductance of Disk Coils and the Optimal Value of Self-Inductance

open access: yesZhongguo dianli, 2019
The disk coils are the core element of energy coupling of the wireless power transmission system blooming in recent years. By introducing generalized hypergeometric functions pFq, the integral expression of self-inductance of disk coils is transformed ...

Theoretical Analysis of Planar Spiral Coils between Two Multilayer Media for Electric Vehicle Wireless Charging

open access: yesEnergies, 2018
Square and circular coils are two typical topologies for coupling coils and are applied to wireless charging. However, most of the research on coupling coils is based on the finite element model (FEM), which is a time-consuming process for 3-D structure ...

Ironic Medications: A Narrative‐Based Psycho‐Educational Intervention to Explore Patient–Provider Communication in Adolescents With Haematological Cancer

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with haematological malignancies face significant emotional and relational challenges, often accompanied by difficulties in communicating their needs within the healthcare context. To address these issues, a narrative‐based psycho‐educational intervention based on the creation and prescription of Ironic Medications was ...
