In this paper, theoretical results are shown for several novel inverters. These inverters are similar to the Z-source inverters presented in previous works, but have several advantages, including in some combination; lower component ratings, reduced source stress, reduced component count and simplified control strategies.

New capacitor assisted quasi Z-source inverter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In this paper, a new quasi Z-source inverter based on new capacitor basic units (CAQZSI) is proposed. It is possible to develop the proposed topology by using n numbers of the basic units that is one of the main advantages of the proposed CAQZSI. The boost factor equation, voltage and current equations of the capacitors, diodes and inductors are ...

Quasi-switched-inductor Z-source inverter
2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016A new Z-source inverter called Quasi switched inductor Z-source inverter(QSLZSI) is presented in this paper. The proposed inverter not only inherits the advantages of traditional Z-source inverters but also has the unique features of capacitor H-bridge circuit: simplified structure, reduced component count, simplified control strategies, higher boost ...

An Extended Quasi-switched Z-Source Inverter
2019 10th International Power Electronics, Drive Systems and Technologies Conference (PEDSTC), 2019In this paper, a new extended quasi-switched Z-source inverter, using a switched-inductor cell, is proposed. The most important advantage of the proposed inverter is achieving the maximum voltage gain in the lower duty cycle with less circuit components than similar previous inverters, which causes the modulation index value increase.

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.

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 Novel Dual Switching Frequency Modulation for Z-Source and Quasi-Z-Source Inverters
IEEE Transactions on Industrial Electronics, 2018Impedance network inverters are the best alternatives for voltage-source and current-source inverters. The boosting capability and the shoot-through solution of such converters make them excellent solutions for various applications. Nevertheless, hard switching forces the converter to operate in low switching frequency, which results in a bulky ...

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.

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 ...

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 ...
