چکیده

We consider the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter ε > 0. An explicit form of the singular part of the corresponding potential u is given. This allows to construct the limit potential u (as ε → 0) and an approximation of the inductance coefficient L. We establish some estimates of the deviation u − u and of the error of approximation of the inductance. The main result shows that L behaves asymptotically as ln ε, when ε → 0.

Asymptotic behaviour of the inductance coefficient for thin conductors

We study the asymptotic behaviour of the inductance coefficient for a thin toroidal inductor whose thickness depends on a small parameter ε > 0. We give an explicit form of the singular part of the corresponding potential uε which allows to construct the limit potential u (as ε → 0) and an approximation of the inductance coefficient Lε. We establish some estimates of the deviation uε −u and of ...

Mutual Inductance of Thin Coaxial Circular Coils with Constant Current Density in Air (Filament Method)

This paper deals with an efficient and fast approach for determining the mutual inductance between thin current loops (filamentary coils, thin cylindrical coils, thin disk coils and all possible combinations). This approach is based on the filament method where conductors are approximated by a set of Maxwell’s coils. The resulting equations are expressed in term of the complete elliptical integ...

Inductance Comparison of the Solenoidal Coil of Modular Toroidal Coils Using the Analytical and Finite Element Method

The modular toroidal coil (MTC) is composed of several solenoidal coils (SCs) connected in series and distributed in toroidal and symmetrical forms. In this paper, we present an accurate approach for calculation of the mutual and self-inductance between all the SCs of MTC with any arbitrary section. We use Biot-Savart’s and Neumann’s equations to calculate the selfand mutual inductance between ...

Mutual Inductance Between Coaxial Circular Coils of Rectangular Cross Section and Thin Coaxial Circular Coils with Constant Current Density in Air (Filament Method)

This paper deals with an efficient and fast approach for determining the mutual inductance between coaxial circular coils of rectangular cross section in combination with thin coaxial circular coils as the thin wall solenoid, the thin disk coil and the filamentary coil. This approach is based on the filament method where conductors are approximated by the set of Maxwell’s coils. The obtained ex...

Analysis of formulas to calculate the AC inductance of different configurations of nonmagnetic circular conductors

The inductance of singleand multi-conductors intended for electronic devices, power transmission and distribution or grounding, lightning and bonding systems greatly depends on the specific geometry and the supply frequency. It is also influenced by skin and proximity effects. The inductance is an important design parameter, since it significantly influences the voltage drop in the conductor, t...
