General theory of multi-leg power conversion circuits based on neutral point voltage
ISIE'2000. Proceedings of the 2000 IEEE International Symposium on Industrial Electronics (Cat. No.00TH8543), 2002This paper describes the general theory of the main circuit constructions and control methods of legs based on output neutral point voltage control under multi-leg power conversion circuits. A controllable fluctuation range of the output neutral point voltage is obtained by the linear programming method under the condition of the desired symmetrical ...

The general fluid circuit theory of active chloride absorption
The Bulletin of Mathematical Biophysics, 1940The original fluid circuit theory used to explain active intestinal absorption of chloride is modified to include diffusion and secretion of chloride and osmosis. The general differential equation developed is integrated in a particular case. The definition, “effective concentration of chloride in the fluid passing into the intestinal lumen,” leads to ...

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 ...

Notice of Retraction: Analysis of Loss Compensation on Generation Rights Trade by Circuit Theory
2010 Asia-Pacific Power and Energy Engineering Conference, 2010The generation rights trade could make the losses change, which should be compensated by the trade participants, so the fair loss compensation principle should be established, it could not only help for confirming the traders' responsibilities, but also help the generation rights trade to develop very quickly. This paper thinks that the key of solution

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
This paper presents a general analysis of the 3rd-order nonlinearity of a single-ended and differential common-emitter (CE) radio frequency (RF) amplifier. With direct computation of the third-order nonlinear response, a closed-form expression was derived. The results suggested several novel ways to cancel the third-order nonlinearity without affecting

An improved FDTD formulation for general linear lumped microwave circuits based on matrix theory
IEEE Transactions on Microwave Theory and Techniques, 2005An improved finite-difference time-domain (FDTD) formulation using the matrix theory is presented to analyze hybrid general linear lumped and distribution microwave circuits. Traditionally, since discrete current expressions of lumped circuits should be substituted into Maxwell's equations explicitly, the different discrete formulations of Maxwell's ...

Designing a Low-Power Generator Circuit with Switching Theory for Power Reduction
2017Testing the VLSI circuits is the major aspect to know the parameter variations at different stages. For the self-testing of the circuits, we introduce a suitable structure which can be used for testing the VLSI designs. The structure is built in such a way that the objective of the generator is highly utilized for the power dissipation reduction which ...

New approach to general theory of electrical machines using magnetic equivalent circuits
Proceedings of the Institution of Electrical Engineers, 1973First, the nature of equivalent circuits and the alternative electric or magnetic equivalents for any electromagnetic system are examined. In the remaining Sections, steady-state and symmetrical sudden short-circuit conditons are analysed for the3-phase synchronous, the 3-phase induction and the compounded d.c.

Journal of Applied Physics, 2009
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 ...

SELF-CONSISTENT FIELD THEORY OF GENERAL PERIODIC CIRCUITS FOR TRAVELING WAVE TUBES
International Journal of High Speed Electronics and Systems, 1993A general method for exact analysis of cylindrical periodic circuits for traveling wave tubes without initial assumptions of field or current distributions is described. The procedure is based on transforming the stationary periodic circuit to Fourier space, in the same manner as one does the ordinary RF fields.
