Switched Impedance Enhanced-Boost Quasi-Z-Source Inverter

2017 14th IEEE India Council International Conference (INDICON), 2017
Enhanced-boost quasi-Z-source inverter (EB-qZSI) is proposed in this paper. Similar to the enhanced-boost ZSI and continuous input current enhanced-boost qZSI with two switched-impedance networks, this proposed inverter topology possess very high voltage boost at low shoot-through duty ratio and high modulation index to provide better quality output ...

Simple boost PWM controlled cascaded quasi Z-source inverter

Materials Today: Proceedings, 2021
Abstract In this paper cascaded quasi Z source inverter is used to give desired boosted output. It can derive from the quasi Z source inverter by adding one diode, one inductor, ant two capacitors. Power converters can be used for adjusting the parameters needed for synchronization of the source and load.

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.

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 ...
