“…If this condition is substituted into (8), it is seen that the Thévenin impedance is equal to the test load impedance as in (9). This approach is used to determine experimentally the output resistance of the amplifier circuits in electronic experiments (10): …”

“…(6)(7)(8)(9). Moad presented the concepts of the Thévenin and Norton theorems and surveyed some textbooks presenting these theorems and gave methods of finding equivalent circuits for two ports and multiterminal networks (10). Haley gave proof of the Thévenin theorem for linear circuits using current-voltage (I -V ) characteristic of the output of the circuits (11).…”

In 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 impedance. All equivalent circuit parameters are derived simultaneously and systematically from the characteristic equation relating to the output of the circuit. © 2011 Institute of Electrical Engineers of Japan.

“…The source description bases on Thevenin's law which describes, that every arbitrary unknown circuitry with active sources can be described with a passive impedance matrix and additional active sources [4]. Thevenin's law is equivalent to the Norton theorem, using the port current values.…”

The filter development process, to reduce occurring conducted emissions, is still an unsolved problem within EMC considerations, due to the filter attenuation depends on the impedance values of the device under test. The paper presents a method how to characterize arbitrary active applications within the frequency domain. The evaluated noise sources are described as Y or Z-matrices with additional active sources in respect to Thevenin's law. Through a translation from the time into the frequency domain even circuits including non-linear elements can be considered. The method is presented for the example of a power stage circuit and it is considered how to translate the technique into measurements.

“…Section II of the paper considers a receiving coil, from here on denoted as "pickup", coupled with only one transmitting coil. General CNs with T topology are considered and the Thevenin and Norton equivalent circuits of the transmitting and the receiving sections of the WPTS are given [19]- [21]. From them, the equations that describe this simple WPTS are derived.…”

The wireless power transfer systems represent a viable solution to make more user friendly the procedure of charging the battery of electric vehicles. The performances of these systems are greatly affected by their compensation networks and are usually studied by considering their first harmonic equivalent circuits. This paper presents a new approach to writing the equations that describe these circuits and expresses them in a form that highlight the contribution of the coupled coils and of their compensation networks. The procedure to obtain the equations is described in details and the equations themselves are analyzed to derive from them the qualitative characteristics of the wireless power transfer system. In the last part of the paper a numerical analysis of a study case is reported, supporting the results by means of simulations.INDEX TERMS Compensation networks, Equivalent circuits, Wireless power transmission.
