Typical Transformer-Based Z-Source/Quasi-Z-Source Inverters
2016This chapter discusses the typical trans and LCCT Z-source/quasi-Z-source inverters (ZSIs/qZSIs). Their configurations, working operations, voltage and current principles, and simulation results are presented, providing a demonstration of the investigation of other extended transformer-based ZSIs/qZSIs.

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.

Switched Capacitor Z-Source Inverter
2016 IEEE 1st International Conference on Power Electronics, Intelligent Control and Energy Systems (ICPEICES), 2016This paper presents a novel inverter topology based on conventional Z-Source Inverter and Switched Capacitor DC-DC converter. Compare to other conventional topologies the proposed topology gives more boosting factor. Further the input current is continuous. In renewable energy conversion system, it is desirable to get high step up output voltage from a

Z-Source Inverter for Photovoltaic Microgeneration
2019 IEEE 15th Brazilian Power Electronics Conference and 5th IEEE Southern Power Electronics Conference (COBEP/SPEC), 2019The number of grid-connected photovoltaic systems has been growing in the world as a sustainable alternative for power generation. This paper presents a study of Z-source inverter applied to a low voltage residential photovoltaic microgeneration system. The ZSI topology is evaluated through the expressions related to its equivalent electrical circuits,

Z-source inverter with neutral point
2013 14th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices, 2013This paper proposes a novel inverter for four-wire systems. The number of used transistors is reduced in a Z-source inverter with neutral point as compared with known schemes of Z-source inverter for four-wire systems. It increases reliability and efficiency. The scheme operation is verified by simulation.

Z-source inverter for motor drives
2004 IEEE 35th Annual Power Electronics Specialists Conference (IEEE Cat. No.04CH37551), 2004This paper presents a Z-Source inverter system and control for general-purpose motor drives. The Z-source inverter system employs a unique LC network in the DC link and a small capacitor on the AC side of the diode front end. By controlling the shoot-through duty cycle, the Z-source can produce any desired output AC voltage, even greater than the line ...

There are two hotly researched Z-source/quasi-Z-source (ZS/qZS) multilevel inverters: the ZS/qZS neutral-point-clamped (NPC) inverter and ZS/qZS cascaded multilevel inverter (CMI). The ZS/qZS concept, integrating with those traditional multilevel inverters, inherits the merits of both topologies with improved inverter reliability due to short-circuit ...
