Matrix converter with a series Z-source
IECON 2012 - 38th Annual Conference on IEEE Industrial Electronics Society, 2012Series Z-source network, an expansion of the popular concept of Z-source dc link, was originally proposed for boosting the output voltage of power electronic inverters. In this paper, that idea is extended onto a three-phase indirect matrix converter.

Switched Z-source DC-DC converter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017In this paper, a switched Z-source dc-dc converter (SZSC) is proposed for the conversion from a low voltage to a higher one in renewable energy systems. The voltage gain is increased by adding another one switch and diode to the output terminal of the traditional Z-source dc-dc converter.

A Family of Z-source and Quasi-Z-source DC-DC Converters
2009 Twenty-Fourth Annual IEEE Applied Power Electronics Conference and Exposition, 2009This paper presents a family of four-quadrant dc-dc converters with minimal number of switches and passive devices. These converters employ a Z-source or a quasi-Z-source network with two active switches to provide four quadrant operation which means bipolar output voltage and bidirectional current operation.

Z-Source Matrix Converter: An Overview
IEEE Transactions on Power Electronics, 2016Conventional matrix converters (MCs) have limited voltage gain that is less than 0.866, whether for direct MC (DMC) or indirect MC (IMC). The Z-source MCs (ZSMCs) overcome the voltage gain limitation of the traditional MC and achieve buck and boost operation with reduced switches count, thereby achieving low cost, high efficiency, and reliability ...

Z-Source Inverter Based on CUK Converter
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 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

Comparison of voltage source converters and Z-source converters for electric vehicles
Emerging Materials Research, 2021Voltage source and current source converters are used in industrial applications as either boost or buck converters for a defined power flow direction. These operational modes limit these converters to be utilized on their own in hybrid and electric vehicle (EV) applications.

Comparative Evaluation of Three Z-Source/Quasi-Z-Source Indirect Matrix Converters
IEEE Transactions on Industrial Electronics, 2015Conventional matrix converters (MCs) have limited voltage gain that is less than 0.866, whether for direct MC (DMC) or indirect MC (IMC). Existing Z-source (ZS)/discontinuous quasi-Z-source (qZS) DMCs and ZS IMCs achieved larger than 0.866 voltage gain; however, the former inherited the complex commutation from DMC, and the latter involved a ZS network

Simplified quasi‐Z source indirect matrix converter
International Journal of Circuit Theory and Applications, 2014SummaryConventional matrix converters have a limited voltage gain less than 0.866 and also require many power switches and additional input filter that ensures a low input current harmonics to the grid. Quasi‐Z source (qZS) indirect matrix converter can provide high voltage gain and ensure a sinusoidal input current without additional input filter ...

A novel quasi‐Z‐source indirect matrix converter
International Journal of Circuit Theory and Applications, 2013SummaryA new type of three‐phase quasi‐Z‐source indirect matrix converter (QZS‐IMC) is proposed in this paper. It uses a unique impedance network for achieving voltage‐boost capability and making the input current in continuous conduction mode (CCM) to eliminate the input filter.
