Z-source networks for power conversion
2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008This paper extends the impedance-source (Z-source) converter/inverter into a broader concept and presents several new impedance-source networks (Z-source networks or Z-networks) for power conversion purpose. The previously presented Z-source network (circuit) consists of two inductors and two capacitors connected in a special arrangement to form a two ...

A review on modulation techniques of Z-source network
2016 7th India International Conference on Power Electronics (IICPE), 2016Impedance source converters, are very fast growing technology for electrical energy conversion and particularly appropriate for distributed energy generation. These network avoid limitation associated with traditional voltage and current source converter by adding additional state, called as shoot-through state.

An approach of sparse matrix converter using Z-source network
The 2010 International Power Electronics Conference - ECCE ASIA -, 2010This paper presents an approach of sparse matrix converter (SMC) using Z-source network. The SMC is implemented by connecting a controllable rectifier and the traditional inverter through a Z-source network. The Z-source can produce any desired output voltage by controlling the shoot-through time.

Three-Level Indirect Matrix Converter With Series Z-source Networks
2020 IEEE PES/IAS PowerAfrica, 2020The concept of series Z-source network has been extended to a conventional indirect matrix converter in previous publications for raising the voltage gain to unity and beyond. In this paper, this idea is adapted and applied to a three-level indirect matrix converter.

A novel sparse matrix converter with a Z-source network
2009 35th Annual Conference of IEEE Industrial Electronics, 2009This paper proposes a novel Z-source sparse matrix converter and its modulation strategy. The proposed matrix converter is developed based on the structure of a sparse matrix converter to reduce the number of unipolar turn-off power semiconductors and employs a Z-source network to overcome the inherent drawback of the low voltage transfer ratio of the ...

PV grid-connected power conditioning system with Z-source network
2009 International Conference on Sustainable Power Generation and Supply, 2009This paper presents a single-phase photovoltaic power conditioning system (PVPC) based on a Z-source impedance network instead of a conventional boost converter. Using Z-source networks, the system can work within a wider range of PV array output voltages than for a conventional boost converter.

An Improved Gain Quasi Z-Source Inverter Employing Active Switched Network
2020 IEEE International Conference on Power Electronics, Smart Grid and Renewable Energy (PESGRE2020), 2020A high gain converter is a prime requirement for low voltage input power application. Z-source inverter has attracted the attention widely. A lot of efforts has been made to improve the voltage gain with better design. However, still there is a gap to achieve higher voltage gain with optimum number of components.

Modified Series and Tapped Switched-Coupled-Inductors Quasi-Z-Source Networks
IEEE Transactions on Industrial Electronics, 2019This paper proposes two coupled-inductors-based Z-source networks, called the modified series and tapped switched-coupled-inductors quasi-Z-source networks (mSSCL-qZSN and mTSCL-qZSN, respectively). These networks offer high voltage gains with less-than-unity winding turn ratios $(n , resulting in a reduced inductive element size.
