Switched-Inductor Quasi-Z-Source Inverter
IEEE Transactions on Power Electronics, 2011This paper deals with a new family of high boost voltage inverters called switched-inductor quasi-Z-source inverters (SL-qZSIs). The proposed SL-qZSI is based on the well-known qZSI topology and adds only one inductor and three diodes. In comparison to the SL-ZSI, for the same input and output voltages, the proposed SL-qZSI provides continuous input ...

Tapped inductor quasi-Z-source inverter
2012 Twenty-Seventh Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2012This paper proposes a high inversion gain single stage boost inverter, which introduces a tapped inductor network into the traditional quasi-Z-source inverter (qZSI), called tapped inductor quasi-Z-source inverter (TL-qZSI). The tapped inductor network including one tapped inductor and two diodes and is used to replace one inductor of the traditional ...

A new topology for quasi-Z-source inverter
2015 30th International Power System Conference (PSC), 2015In 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.

Improved performance of the switched inductor quasi Z-source inverter
2016 11th International Conference on Industrial and Information Systems (ICIIS), 2016This paper proposed the improvement of switched-inductor quasi-Z-source inverters (SL-qZSIs) with different control technique. SL-qZSIs adds only one inductor and three diodes as compare to the quasi z-source inverter but as compare to qZSI boost factor is high in SL-qZSI.

Grid connected quasi-Z-Source direct matrix converter
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper proposes a new three-phase ac-ac converter topology based on the Z-source concept and the conventional direct matrix converter (DMC), it is called quasi-Z-Source direct matrix converter (QZSDMC). It could provide buck-boost function and make the role of frequency changer.

A Digital Current Control of Quasi-Z-Source Inverter With Battery
IEEE Transactions on Industrial Informatics, 2013This paper presents a fixed frequency operating sliding mode (SM) current control method with fast response and improved stability. Different from the conventional SM control with variable switching frequency, the fixed-frequency SM controller is proposed to control the modulation index and shoot-through duty ratio of the voltage-fed quasi-Z-source ...

Bidirectional cascaded quasi-Z-source DC-DC converter
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper proposes bidirectional cascaded quasi-Z-source dc-dc converter (BC-qZSC). Compared to the traditional cascaded quasi-Z-source network (C-qZSN), the diodes in C-qZSN are replaced by active switches with a parallel diode. BC-qZSC has the higher boost ability and the lower input current ripple than those of the bidirectional quasi-Z-source dc ...

Loss Analysis of Quasi Z-source Inverter with Superjunction-MOSFET
IEEJ Transactions on Industry Applications, 2018AbstractA 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 ...

Modeling and Control of Single-Phase Quasi-Z-Source Inverters
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018Compared with a conventional two-stage inverter, the quasi-Z-source inverter (qZSI) has several advantages for renewable applications because of its buck-boost capability and continuous input current. This paper addresses modeling and control issues resulted from the impedance-source network resonance. Considering shoot-through states, null states, and
