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.

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 ...

An Improved $Z$-Source Inverter
IEEE Transactions on Power Electronics, 2011This 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.

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 ...

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 ...

As the oldest impedance source inverters, Z-source inverter is one of the typical topologies, whose analytical and control methods can be transplanted to other impedance source inverters. Besides, since the impedance source inverters are improved from traditional voltage source and current source inverters by inserting an impedance network, they can be

Comparison of Traditional Inverters and Z-Source Inverter
IEEE 36th Conference on Power Electronics Specialists, 2005., 2006In 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 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 ...

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.
