Mutual Inductance and Force Exerted between Thick Coils
Abstract—We present exact three-dimensional semi-analytical expressions of the force exerted between two coaxial thick coils with rectangular cross-sections. Then, we present a semi-analytical formulation of their mutual inductance. For this purpose, we have to calculate six and seven integrations for calculating the force and the mutual inductance respectively. After mathematical manipulations...
متن کاملMutual 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...
متن کاملMutual Inductance Calculation between Misalignment Coils for Wireless Power Transfer of Energy
In this paper we present a detailed theoretical analysis of lateral and angular misalignment effects in RF coils. Radio-frequency (RF) coils are used extensively in the design of implantable devices for transdermal power and data transmission. A design procedure is established to maximize coil coupling for a given configuration to reduce the effects of misalignment on transmission efficiency. F...
متن کاملEvaluation of the Magnetic Fields and Mutual Inductance between Circular Coils Arbitrarily Positioned in Space
This paper presents the evaluation of the magnetic fields and mutual inductance between circular coils arbitrarily positioned in space. Firstly, based on an advanced and relevant model available in the literature, MATLAB code is implemented to evaluate the mutual inductance between circular coils arbitrarily positioned with respect to each other. The computed results are compared with the numer...
متن کاملComputation of the Mutual Inductance between Air-Cored Coils of Wireless Power Transformer
Wireless power transfer system is a modern technology which allows the transfer of electric power between the air-cored coils of its transformer via high frequency magnetic fields. However, due to its coil separation distance and misalignment, maximum power transfer is not guaranteed. Based on a more efficient and general model available in the literature, rederived mathematical models for eval...
