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

A Novel SEPIC-Based Z-Source Inverter
IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018This paper proposes a new three-switch single-phase Z-source inverter (ZSI) based on SEPIC converters, which can be named SEPIC-based ZSI. This topology has the characteristics of buck-boost capability and has the feature of dual grounding. In addition, the voltage gain of proposed inverter is higher than that of the single-phase quasi-Z-source and ...

Carrier-based PWM for Z-Source Inverters
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Z-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.

Maximum Boost Control of the Z-Source Inverter
IEEE Transactions on Power Electronics, 2004This paper explores control methods for the Z-source inverter and their relationships of voltage boost versus modulation index. A maximum boost control is presented to produce the maximum voltage boost (or voltage gain) under a given modulation index. The control method, relationships of voltage gain versus modulation index, and voltage stress versus ...

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, 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 ...

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.
