“…From the sys~em of equations(11), by the knowledge of the line characteristics (y, Zc), it is possible to write directly the values of the series and parallel impedances of both the "T" and the "half-T" ladder networks which form each quadrupole which models the unity-length transmission line. The total equivalent model is formed by a cascade of L single equal quadrupoles, where L is the line length.…”

In this work, the transmission line modelling by a discrete passive network is considered from a new point of view. The line is modeled by a cascade of quadrupoles, whose internal topology is realized with a ladder network. In the paper, it is shown how a ladder symmetrical topology (the "T" ladder network) approximates well the transmission line behavior, while a not-symmetrical structure, the more commonly used "half-T" ladder network, is less precise. A numerical example, with the help of software simulations, confirm the theory here proposed.

“…Thus, roughly estimated, is the maximum percentage of computing times possibly saved. The actual amount of time saving must be If the RUM method is applied to the transmission line-based loss-free resistor [24], [25] in which the transmission line is realized by a cascade of 12 LC units, the dimension of the formulated RUM for this LC link will be 2 2, instead of 24 24 for the MNM. The simulation speed will be remarkably improved.…”

A new and simple formulation method for switched networks in the numerical time domain is presented. Unification models of switching devices, companion models of energy-storage elements, and several straightforward circuit-manipulated operations are used in obtaining a reduced unification matrix (RUM). The feature of the constant formulated RUM is clarified, and the selection of the main parameters of unification models is illustrated. A condition of reducibility is proposed to determine how small the dimensions of a modified nodal matrix (MNM) can be reduced to. Simulation results using the RUM method demonstrate its superiority over the commonly used MNM method, not only for memory requirements, but also for computational speed. A large circuit example shows that the RUM method offers a 76.32% time savings in computation. Additionally, the RUM method possesses the merits of easy formulation, easy programming and more realistic switch modeling, as well as greater accuracy and higher time efficiency when compared with commonly used state-space approaches. These combined advantages should make the proposed RUM method very attractive in the time-domain simulation of switched networks. For large switched networks, the decided advantages are very great.

“…Prior to the adoption of the LFR in this system, the parasitic pulses had been dissipated in a conventional resistor; otherwise it would have damaged the laser tube. By replacing the conventional resistor with an LFR (a transmission line based one), 85% of the energy was recovered [5], [6]. The LFR can also be applied in photovoltaic systems as a basic building block of a maximum power point tracker.…”

Realization of a loss-free resistor element (i.e., element with resistive input characteristic and yet loss-free) by means of switched mode converters operated in discontinuous current conduction mode (DCM) is presented. Practically, the input characteristic is not pure resistive due to the ripple and filtering effects. A method which enables reduction of the ripple to negligible values and the elimination of the input filter is presented, which facilitates realization of practical circuits with nearly pure input resistive characteristic. This approach is based on the operation of a group of converters operating in power sharing interleaved mode.Index Terms-Active power factor, gyrator, loss-free resistor (LFR), low harmonics rectifier, time variable transformer (TVT), two-port power conservative, unity power factor.
