Dual Active-Switched-Capacitor Quasi-Z-Source Inverter

2019 IEEE Conference on Energy Conversion (CENCON), 2019
This paper proposed a new qZSI topology called dual active-switched-capacitor qZSI (DASC-qZSI). This new proposed topology offers high voltage gain and boost factor value by using less components. In this paper, the proposed topology will be analyzed and compared with previous high boost qZSI topology.

A new topology for quasi-Z-source inverter

2015 30th International Power System Conference (PSC), 2015
In this paper, a new circuit is proposed for step-up Z-source inverter based on QZSI (quasi-Z-source inverter). The proposed topology inherits all advantages of the conventional topology. The proposed topology in comparison with conventional topology reduces the ST (Shoot-through) duty cycle by over 25% at the same voltage boost factor.

Cascaded Three-phase Quasi-Z Source Photovoltaic Inverter

2018 8th International Conference on Power and Energy Systems (ICPES), 2018
A multiplexed inverter topology cascaded by line voltage is proposed, which composes three modules: PV panel, quasi-z source network and three-phase inverter. Through an analysis of the function feature of established mathematical model, an improved dual-loop control system is proposed.

Loss Analysis of Quasi Z-source Inverter with Superjunction-MOSFET

IEEJ Transactions on Industry Applications, 2018
AbstractA Z‐source inverter (ZSI) can work as an inverter with boost capability in one stage by using its impedance source and the short‐through mode as the switching mode. This paper discusses the circuit losses that depend on the boost ratio between the quasi ZSI, which is one of the ZSI topologies, using Superjunction‐MOSFETs and the conventional ...
