Characteristic equation‐based computation of Thévenin and Norton equivalent circuits

IEEJ Transactions on Electrical and Electronic Engineering, 2011
AbstractIn this paper, a new method is proposed for determining the parameters of Thévenin and Norton equivalent circuits. The method is unified and employs only one topology that depends on the test load impedance,Zx, connected to the output of the circuit. It does not require setting all independent sources to zero for determining Thévenin and Norton

THEVENIN EQUIVALENT CIRCUITS FOR MODELING COMMON-MODE BEHAVIOR IN POWER ELECTRONIC SYSTEMS

2021
The high-frequency switching of transistors in power electronic (PE) converters is known to cause unintended common-mode (CM) current that flows through parasitically-coupled ground paths. One way to model these currents is to utilize time-domain simulations that capture switching dynamics and the corresponding parasitic response.

Force and electrical Thevenin equivalent circuits and simulations for thickness mode piezoelectric transducers

The Journal of the Acoustical Society of America, 1975
A simple model is reported for thickness-mode piezoelectric elements used as ultrasonic transducers in measurement systems. The model represents the excitation system and transducer as a Thevenin mechanical equivalent for the transmitting mode and a Thevenin electrical equivalent for the receiving mode.

Thevenin equivalent circuit for the study of high photovoltaic penetration in distribution grids

IEEE PES ISGT Europe 2013, 2013
The electricity grid is unidirectional operating in a passive way and consequently it is not yet ready to accept high penetration of renewable energy sources (RES). Further research is required to assess the impact of distributed Photovoltaic (PV) generation on power quality and establish the necessary measures for the restructuring of the electricity ...

Hybrid equivalent circuit, an alternative to Thevenin and Norton equivalents, its properties and applications

2009 52nd IEEE International Midwest Symposium on Circuits and Systems, 2009
A new two-terminal circuit modeling is presented. This equivalent circuit, called Hybrid equivalent circuit or simply H-model, can replace a Thevenin or a Norton equivalent circuit, which both are shown to be two special cases of an H-model. The H-model contains both voltage and current sources and is shown to be very flexible and dynamic. For students

Thevenin equivalent circuit-based time domain simulation for conducted EMI in lossy transmission lines

2002 3rd International Symposium on Electromagnetic Compatibility, 2003
This paper presents a time domain simulation model for conducted electromagnetic interference (EMI) in lossy transmission lines. The lossy lines are divided into a small number of ideal sections for which the Thevenin equivalent circuits substitute, and between these sections the resistances and conductances are connected on behalf of the loss of lines.

A Parameter Extraction Method for the Thevenin Equivalent Circuit Model of Li-ion Batteries

2019 IEEE Industry Applications Society Annual Meeting, 2019
This paper presents a novel parameter extraction method for the Thevenin equivalent circuit model of Lithium-ion batteries. The proposed approach represents each of the RC parallel branches of the Thevenin equivalent circuit model of a Lithium-ion battery as a first order linear time-invariant (LTI) system.

Limitations of the Thevenin and Norton equivalent circuits for a receiving antenna

IEEE Antennas and Propagation Magazine, 2003
The investigation carried out in this paper was stimulated by a recent paper published by Love (2002), in which the appropriateness of the use of the Thevenin and Norton equivalent circuits for a receiving antenna was questioned. A review of the available literature led to the conclusion that the limitations inherent in the Thevenin and Norton ...

New method of finding Thevenin equivalent circuits for the transformer and partial–ideal operational amplifier system

International Journal of Electrical Engineering & Education, 2019
This paper proposes a new method of finding the Thevenin equivalent circuits for the transformer and partial–ideal operational amplifier systems that have not been systematically solved by traditional approaches now. This paper also exploits some strong improvements to solve the complicated dependent source circuit and mutual coupling circuit.

Comment on "Limitations of the Thevenin and Norton equivalent circuits for a receiving antenna"

IEEE Antennas and Propagation Magazine, 2003
The author comments that Collin (see IEEE Antennas and Propagation Magazine, vol.45, p.119-124, 2003) points out some of the attributes of the constant-power equivalent circuit for a receiving antenna. However, he disagrees with the writer's statement that the internal power dissipated in the circuit can be equated to the reradiated, or scattered ...
