Z-Source Inverter Based on CUK Converter

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
This paper proposes a new three-switch single-phase Z-source inverter (ZSI) based on CUK converter, which is named CUK-based ZSI. This topology has the characteristics of buck-boost capability and dual grounding. In addition, the voltage gain of proposed inverter is higher than those of the single-phase quasi-Z-source and semi-Z-source inverters. Aside

Carrier-based PWM for Z-Source Inverters

IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012
Z-Source Inverters have the ability to boost the dc link voltage, thus increasing the output ac voltage beyond the values reached by conventional inverters. The enhanced ratio from ac output voltage to dc link voltage is possible due to an impedance network connected between the dc power supply and the main converter.

LCCT-Z-Source inverters

2011 10th International Conference on Environment and Electrical Engineering, 2011
Many renewable generation units (e.g. PVs, fuel cells, small wind turbines) require integrated DC-AC converters providing efficient high step-up power conversion. On the basis of recent developments in impedance source (Z-source) inverters the present paper proposes an integration of quasi-Z-source inverter (qZSI) with a built-in high frequency ...

A comparison of Z-Source three-level NPC inverter versus Z-Source two-level inverter

2010 Emobility - Electrical Power Train, 2010
The Z-Source inverter enables a single stage buck-boost conversion which is a useful characteristic in battery supplied electric vehicles. However, the boost operation leads to additional losses in the semiconductors of the inverter. This paper presents a comparison of Z-Source two-level inverter and Z-Source NPC inverters with regard to their total ...

Z-source inverter with neutral point

2013 14th International Conference of Young Specialists on Micro/Nanotechnologies and Electron Devices, 2013
This 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.

Four quasi-Z-Source inverters

2008 IEEE Power Electronics Specialists Conference, 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.
