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, 2009The 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.

Single-phase Z-source inverter
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008This 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.

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), 2019This 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.

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 ...

Switched Inductor Z-Source Inverter
IEEE Transactions on Power Electronics, 2010On the basis of the classical Z-source inverter, this paper presents a developed impedance-type power inverter that is termed the switched inductor (SL) Z-source inverter. To enlarge voltage adjustability, the proposed inverter employs a unique SL impedance network to couple the main circuit and the power source.

4th Annual International Power Electronics, Drive Systems and Technologies Conference, 2013
In recent years, five leg inverter and nine switch inverter have been proposed. Those can independently control two three-phase loads. This paper proposes a novel structure for Five-Leg Inverter (FLI) named Z-source FLI. This inverter has ten switching devices and can independently control two three-phase loads with high voltage range.
