IEEE Transactions on Power Electronics, 2016 A novel A-source impedance network is proposed in this paper using an autotransformer for realizing converters that demand a very high dc voltage gain. The network utilizes a minimal turns ratio compared to other Magnetically Coupled Impedance Source (MCIS) networks to attain high voltage gain.

This paper introduces a Y-shaped impedance network for realizing converters that demand a high voltage gain while using a small duty ratio. To achieve that, the proposed network uses a tightly coupled transformer with three windings, whose obtained gain is presently not matched by existing networks operated at the same duty ratio.

Determination of the Impedance Matching Domain of Impedance Matching Networks
IEEE Transactions on Circuits and Systems Part 1: Regular Papers, 2004This paper investigates the impedance boundary of impedance matching networks analytically, graphically representing the resultant impedance matching domains. A set of explicit equations is derived to allow the rapid development of the impedance boundary of such networks.

Drawbacks of impedance networks
International Journal of Circuit Theory and Applications, 2017SummaryThis paper presents the influence of voltage‐fed impedance networks, known as Z‐source and quasi–Z‐source, as well as some more sophisticated networks on the static and dynamic properties of voltage source inverters. The impedance networks increase output voltage distortions with the second harmonic of the fundamental harmonic and decrease the ...

On The Equivalent Impedance of Two-Impedance Self-Similar Ladder Networks
IEEE Transactions on Circuits and Systems II: Express Briefs, 2021Recurrent ladder network models are encountered in the analysis of many natural systems including wave propagation in transmission lines, porous electrode/electrolyte interfaces and viscoelastic (bio)materials. Here we re-visit the equivalent impedance of self-similar ladder networks composed of two arbitrary impedances recursively arranged, with the ...
