The possibilities of using magnetic, instead of electric, equivalent circuits for eddy-current devices, which have recently been pointed out by Laithwaite, are here explored further. Couplings between distributed flux paths and windings can be expressed in terms of a generalised linkage parameter N, which is associated with flux linkage in electric ...

Equivalent circuits in stability studies
Electrical Engineering, 1934Representation of ``receiving-end'' systems by simplified equivalent circuits, for use in steady state stability studies of electric power transmission systems, is discussed in this paper. Various methods of approximate representation are analyzed, compared, and evaluated.

Transistor equivalent circuits
Proceedings of the IEEE, 1959This paper surveys the history of the electric-circuit representation of the transistor over the past fifty years. During the first two decades after the transistor was announced in 1948, primary emphasis was on small-signal equivalent circuits, which could be used for linear-circuit analysis and design.

Equivalent Circuits of Imperfect Condensers
Transactions of the American Institute of Electrical Engineers, 1931Imperfect condensers usually are represented by equivalent electrical circuits consisting either of a pure capacitance and a resistance in series or by a pure capacitance and a resistance (or conductance) in parallel. Algebraic relationships existing among these circuit parameters are well known and commonly are used in dielectric study and electric ...

Equivalent Sequential Circuits
IRE Transactions on Circuit Theory, 1959Three types of sequential circuits are defined, two of which are synchronous and one of which is asynchronous. The concept of equivalent sequential circuits as discussed by Huffman, Mealy, and Moore is extended to circuits of different types. Transformation procedures are given for transforming a state table of one type into state tables of the other ...

The transistor equivalent circuit can now be evolved with the two-pole formulae for the transistor fundamental circuit in Fig. 3.1, the common emitter circuit. We learn from Equation (5.12) that the output voltage v2 results from the initial voltage v1/D which is split at the voltage divider R i , R L and appears at R L as a voltage drop.

Equivalent circuit for birdcage resonators
Magnetic Resonance in Medicine, 1993AbstractWe present an equivalent circuit analysis for both low pass and high pass birdcage resonators loaded with lossy samples. In a generalization of the method of Hoult and Lauterbur (J. Magn. Reson. 34, 425 (1979)), we also derive circuit component values by application of the laws of electrodynamics.

During the last decade, there has been a shift in emphasis in device modelling research away from equivalent circuits and in favour of numerical device simulation. This has been driven by a rapid increase in the computing power to cost ratio and the assertion that the solution of the fundamental device equations is required to adequately model modern ...

Nonlinear equivalent circuits for membranes
Journal of Mathematical Biology, 1984The problem of obtaining Helmholtz equivalents for nonlinear resistive one-ports is considered. Two fundamentally different classes of equivalent are described, one local and the other global. For each, necessary and sufficient conditions are derived for the existence and uniqueness of either the Thévenin equivalent or the Norton equivalent or both ...

Equivalent Circuit Programming
2019Optimal decision-making processes represent the key component of everyday life and can be found everywhere, from the atomic level in nature, to the emerging technologies that are becoming increasingly dependent on various Machine Learning algorithms and Artificial Intelligence. Consequently, finding the mathematical modeling formulations and algorithms
