Three Phase Trans-Quasi-Z-Source Inverter
CPSS Transactions on Power Electronics and Applications, 2018 In this paper, a new type of single-stage boost Transquasi- Z-source inverter topology is presented. The basic structure and working principle of the inverter are analyzed and its voltage gain is deduced. The model of the Trans-quasi-Z-source network is established by using Laplace transform.

Quasi Z‐source inverter with switched‐capacitor‐inductor for enhancing boost factor
IET Power Electronics, 2021 Two structures are proposed based on the quasi Z‐source inverter (qZSI), which can significantly raise the output voltage in applications, including photovoltaic and fuel cells, in which the input voltage is low.

New Multicell Switched-Inductor Quasi-Z-Source Inverter
Electronics, 2023 To address the problems of quasi-Z-source inverters with limited boosting ability and high voltage stress, a novel class of multicell switched-inductor quasi-Z-source inverters is proposed. The new inverter is based on the quasi-Z-source inverter in which the inductors in the impedance source network are replaced by a multicell switched-inductors.

Large-signal stability conditions for semi-quasi-Z-source inverters: switched and averaged models
, 2013 The recently introduced semi-quasi-Z-source in- verter can be interpreted as a DC-DC converter whose input- output voltage gain may take any value between minus infinity and 1 depending on the applied duty cycle. In order to generate a sinusoidal voltage

Analysis and modeling of the Quasi-Z-Source-Inverter
IECON 2011 - 37th Annual Conference of the IEEE Industrial Electronics Society, 2011 This paper presents a dynamic average model of the Quasi-Z-Source Inverter (QZSI), based on the short term average values over one PWM-period, and the analysis of the possible switching states that can occur in the QZSI. The model is considerably descriptive since the modeling has been performed by analyzing the physical and functional relations with ...
