The general theory for analysis of subharmonic oscillations at a frequency of ω/3 in three-phase ferroresonance circuits is presented. The occurrence and existence of ferroresonance oscillations at subharmonic frequencies in power transmission lines and power supply systems is highly undesirable, since they cause overvoltages at various frequencies. At

A generalized theory of transistor bias circuits
Transactions of the American Institute of Electrical Engineers, Part I: Communication and Electronics, 1958ONE of the important problems met in the design of transistor circuits is how to arrange the bias network to obtain the proper operating point and how to maintain this condition within specified limits, subject to environmental changes such as temperature, or to a range of parameters due to production spread in device manufacture. Several bias circuits

A general transformation with applications to circuit theory
Journal of the Franklin Institute, 1968Abstract A general functional transformation is introduced and some applications to circuit theory are given. The transformation is most useful in the area of active, nonbilateral circuits. This functional transformation introduces new voltages and currents which are linear combinations of the original voltages and currents plus their derivatives ...

A generalized equivalent circuit in the theory of polyphase commutator motors
Electrical Engineering, 1941The demand for speed variation and power-factor compensation in a-c motors led to the development of the polyphase commutator types. In their simplest form these motors consist of two windings; a stator winding which is identical with that of the polyphase induction motor and a rotor winding of the closed type provided with a commutator and similar to ...

A General Theory of Circuit Analogy in Fracture Diagnosis.
1984Abstract : The present report develops electrical analogs to investigate multiple cracks on simple beams and more complex frame structures. Analog networks provide the economic tool to analyze such structures. The effect of multiple cracks on the natural frequencies of simple structures is studied in detail.

We generalize Kirchoff’s law for multiply connected wire networks to finite frequencies. We focus on the boundary conditions not present in the conventional Kirchoff’s law at joints when more than three wires come together, which is absent in our previous “circuit theory” for the finite frequency properties of metallic wire networks for singly ...

Elements of general theory of null-balance circuits
1998 Midwest Symposium on Circuits and Systems (Cat. No. 98CB36268), 2002The null-balance method of output indication is widely used in instrumentation techniques and sensor applications. Yet, the theorems and methods of general circuit theory that are the basis of the null-circuit analysis and design have nearly disappeared from the modern books on network theory.
