Analytic Mapping between Porous Electrode Theory and Equivalent Circuit

ECS Meeting Abstracts, 2020
Battery equivalent circuit models (ECMs) are frequently used in battery management systems of high end applications due to their low computational complexity, robustness and simplicity. Nevertheless, empirical nature of such models and lack of physiochemical background calls for excessive experimental parametrization of the ECMs to ensure their ...

An analytical model for squirrel cage induction machine with broken rotor bars derived based on the multiple coupled circuit theory and the winding function approach

International Journal of Circuit Theory and Applications, 2021
SummaryIn this paper, a squirrel cage induction machine (SCIM) with broken rotor bars is modeled by using the multiple coupled circuit theory and the winding function approach. This analytical model includes all the spatial harmonic components of air gap magnetomotive force and is applicable to the study of transient machine behaviors.

An Analytical Method of Current Distribution Factors Based on Circuit Theory

2010 Asia-Pacific Power and Energy Engineering Conference, 2010
This paper proposes a current distribution theory based on classical circuit theory. According to interface power flow, the distribution current from source to branch circuit can be clarified by using current distribution factors through network structure parameter. This method is conducive to economic dispatch and power flow analysis.

J-EXPANDING MATRIX FUNCTIONS AND THEIR ROLE IN THE ANALYTICAL THEORY OF ELECTRICAL CIRCUITS

Russian Mathematical Surveys, 1973
Chapter I establishes the essential properties of the -matrix of a passive multipole depending on the number of its branches. These properties are based on Langevin's theorem.A classification of the basic objects of investigation: -expanding matrix-functions (class ), and also positive matrix functions (class ), is introduced.Chapter II gives an ...

Analytical theory and equivalent circuit for extraordinary transmission through arrays of slits perforated in realistic metallic screens

2010 URSI International Symposium on Electromagnetic Theory, 2010
We propose an analytical theory of extraordinary optical transmission (EOT) through lossy metallic screens perforated by a periodic array of subwavelength slits. The theory is based on our previous work on EOT through perfect conducting screens and on the surface impedance concept.

Revisiting the analytic theory of p-n junction impedance: improvements guided by computer simulation leading to a new equivalent circuit

IEEE Transactions on Electron Devices, 1999
We revisit the analytic derivation of the dc and low frequency ac behavior of the p-n step junction and suggest all preexisting treatments are flawed for three important reasons. First, not all contributions to the diode current are included. We derive a rigorous expression for each component of current that can be used to judge the completeness of ...

An Analytic Theory for the Evans Circuit for Avalanche Diodes (Correspondence)

IEEE Transactions on Microwave Theory and Techniques, 1970
An analytic theory is outlined for the operation of avalanche diodes in the circuit first analyzed by Evens. This consists of a low-pass filter situated approximately one-half wavelength from the diode. The magnitude and rate of rise of the voltage for a given charge pulse are estimated, and expressions for the efficiency and diode impedance are ...

Analytical model for ideal generic memristor circuits based on the theory of Volterra

2015
The use of memristors in future electronics is under deep investigation nowadays. The fields where these devices may find application are various. In fact there exist distinct types of memristors. Depending upon materials and operating conditions, different physical phenomena may emerge in these two-terminal devices, and the resulting dynamics may ...

Analytical theory, circuit and numerical simulations to design a splittable degenerate birdcage for MSK applications

2016
The degenerate birdcage is not a common design for ultra-high field transmit array due to the technical difficulties in its construction, such as the interdependence of tuning and degeneracy on the value of capacitors. We present here a combination of an analytical theory, circuit simulations and numerical simulations to be used for an efficient design
