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 ...

High boosting type Z-source inverter/ improved Z-source inverter for solar photovoltaic system
2015 Annual IEEE India Conference (INDICON), 2015In this paper, two topologies are presented for solar PV system, namely voltage lifting ZSI and voltage lifting Improved ZSI. These proposed inverters possess very high voltage boost. By replacing the middle diode in one of the switched inductor (SL) cell of SL-ZSI/2SL-qZSI with capacitor (CVL) high voltage gain can be obtained and also number of L, C ...

A comparison of Z-Source three-level NPC inverter versus Z-Source two-level inverter
2010 Emobility - Electrical Power Train, 2010The 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 ...

IEEE Transactions on Power Electronics, 2014
On the basis of the classical Z-source inverter (ZSI), this paper presents a novel ZSI which only contains inductors and diodes in Z-source network. The inverter uses a unique inductor and diode network for boosting its output voltage, provides a common ground for the dc source and inverter, and avoids the disadvantage causing by capacitor in the ...

Z-Source Inverter for Motor Drives
IEEE Transactions on Power Electronics, 2005This 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 ...

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.

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.
