Origins of the equivalent circuit concept: the voltage-source equivalent [PDF]

Proceedings of the IEEE, 2003
This paper describes the development of the voltage-source equivalent circuit. A subsequent paper concerns the current-source equivalent and summarizes the story. The formal roots of equivalent circuits are Ohm's Law, Kirchoff's Laws, and the Principle of Superposition.

Equivalent Circuits-2 Coupled Circuits

Transactions of the American Institute of Electrical Engineers, 1936
An equivalent circuit to represent 2 coupled circuits having distributed self -and mutual impedance and admittance is developed in this paper for the general case, and modified for certain specific cases. The application of these equivalent circuits for representation of coupled power circuits or a coupled power circuit and ground wire or metallic ...

Transistor equivalent circuits

Proceedings of the IEEE, 1959
This 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-I

Transactions of the American Institute of Electrical Engineers, 1932
Equivalent circuits have been found valuable in the solution of certain problems in that they simplify the analysis. Furthermore, equivalent circuits provide a means of replacing magnetic coupling with simple impedance links thereby permitting the use of the calculating board for solution.

Equivalent Circuits of Imperfect Condensers

Transactions of the American Institute of Electrical Engineers, 1931
Imperfect 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 circuit model for superconductors

IEEE Transactions on Appiled Superconductivity, 2003
We propose an equivalent circuit model that describes the behavior of a superconductor viewed by an external user, for whom the global variables voltage and current are of interest. It is used in time-continuous simulations and it treats well both the subcritical and supercritical current regime.

Equivalence Checking of Reversible Circuits

2009 39th International Symposium on Multiple-Valued Logic, 2009
Determining the equivalence of reversible circuits designed to meet a common specification is considered. The circuits' primary inputs and outputs must be in pure logic states but the circuits may include elementary quantum gates in addition to reversible logic gates.

Equivalent circuits in stability studies

Electrical Engineering, 1934
Representation 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.
