A Class of Quasi-Z-Source Inverters

2008 IEEE Industry Applications Society Annual Meeting, 2008
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.

Single-phase Z-source inverter

2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008
This paper proposes a novel single-phase Z-source inverter topology with input and output sharing the same ground. It is simple in structure and only utilizes two switches while keep the voltage transfer ratio the same as the full-bridge inverter.

An improved strategy for Z source inverter

2017 13th IEEE International Conference on Control & Automation (ICCA), 2017
Due to the advantage of realizing the boost converter, allowing the inverter working in the straight through state, Z source network inverter had been widely applied. However, the disadvantages of Z source Inverter, such as low boost capability and start-up impact, have restricted its development.

Z-Source B4 Inverters

2007 IEEE Power Electronics Specialists Conference, 2007
Inverters designed using reduced active semiconductor devices can be of interest to the industry because of their lower cost and enhanced reliability linked to their less complex gating and control circuitries. Despite their simplicity, most of the reduced component count inverters reported to date can only either perform voltage-buck or boost ...

Extended-Boost $Z$-Source Inverters

IEEE Transactions on Power Electronics, 2009
The Z-source inverter has gained popularity as a single-stage buck-boost inverter topology among many researchers. However, its boosting capability could be limited, and therefore, it may not be suitable for some applications requiring very high boost demand of cascading other dc-dc boost converters.

Comparison of Traditional Inverters and Z-Source Inverter

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
In this paper, three different inverters-traditional PWM inverter, dc/dc boosted PWM inverter, and Z-source inverter were investigated and compared using fuel cell vehicle and photovoltaic domestic application as examples. Total switching device power, passive component requirement, and constant power speed ratio of each of these inverters were ...

A Comparison Between Quasi-Z-Source Inverter and Active Quasi-Z-Source Inverter

2019 10th International Conference on Power Electronics and ECCE Asia (ICPE 2019 - ECCE Asia), 2019
This paper presents some comparative results between the three-phase quasi-Z source inverter (qZSI)and active quasi-Z source inverter (AqZSI). An improved PWM method is proposed for AqZSI. The voltage gain can be increased by using the shoot-through duty cycle and the switching ratio of the additional switch.

Z-source inverter

Conference Record of the 2002 IEEE Industry Applications Conference. 37th IAS Annual Meeting (Cat. No.02CH37344), 2003
This paper presents an impedance-source (or impedance-fed) power converter (abbreviated as Z-source converter) and its control method for implementing DC-to-AC, AC-to-DC, AC-to-AC, and DC-to-DC power conversion. The Z-source converter employs a unique impedance network (or circuit) to couple the converter main circuit to the power source, thus ...

An Improved $Z$-Source Inverter

IEEE Transactions on Power Electronics, 2011
This paper proposes an improved Z-source inverter topology. Compared to previous Z-source inverter topology, it can reduce the Z-source capacitor voltage stress greatly, and has an inherent limitation to inrush current. The control strategy is exactly the same as the previous one, so all existing control strategies can be used directly.
