Comments on "A unified and efficient approach for determining Thevenin (Norton) equivalent circuits

IEEE Transactions on Education, 1991
The commenters suggest that the unified approach of L. Jin and S. Chan in the above-titled work (ibid., vol.32, no.3, pp.408-410, 1990) has inefficiencies and limitations. The r model approach, which eliminates the inefficiencies and limitations of the unified approach is discussed. >

One-step Evaluation of the Thevenin Equivalent Circuit

IETE Journal of Education, 2003
In the usual procedure to determine the Thevenin equivalent of a network N, two separate analyses are needed, one for finding the open-circuit voltage and the other for the evaluation of the Thevenin impedance. This note outlines a method to accomplish this task after the analysis of a single network.

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 ...

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 ...

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

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.

Calculating short-circuit currents in distribution systems via numerically computed Thevenin equivalents

2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004
Distribution system circuit topologies, connections, and equipment pose interesting challenges to system analysts. An approach based upon fundamental circuit analysis principles to calculating fault currents of various types is presented. The basic approach consists of obtaining the prefault phase voltages and a phase Thevenin matrix at the fault ...

Remarks on "Comments on the limitations of the Thevenin and Norton equivalent circuits for a receiving antenna"

IEEE Antennas and Propagation Magazine, 2003
Collin (see IEEE Antennas and Propagation Magazine, no.45, p.119-124, 2003) remarks that Love (see IEEE Antennas and Propagation Magazine, vol.45, no.4, p.98-99, 2003) has misinterpreted his. In the paper under discussion, he did not discuss the efficiency of a receiving antenna or give any comment on the maximum efficiency a parabolic receiving ...

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.

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.
