A Z-Source Half-Bridge Converter
IEEE Transactions on Industrial Electronics, 2014Applying an LC network into a half-bridge converter, a novel Z-source half-bridge converter is presented, in which less LC components are needed compared to the conventional one. This Z-source half-bridge converter can solve not only the problems of the shoot-through and limited voltage but also the problem of imbalance at the midpoint voltage of input

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 ...

Current-fed Z-source matrix converter
2009 International Conference on Applied Superconductivity and Electromagnetic Devices, 2009This paper proposes a current-fed Z-source matrix converter topology. It combines the current-fed Z-source ac-ac converter with traditional current-fed matrix converter, and can overcome the conceptual and theoretical barriers and limitations of the traditional matrix converter. It can output lower voltage and has higher reliability.

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.

Photovoltaic lighting system based on Z-source/quasi-Z-source converter topology
2011 Twenty-Sixth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2011This paper proposes a photovoltaic lighting system based on a power converter that combines the Z-source and the quasi-Z-source topologies. When there is enough sunlight the power converter operates similarly as the quasi-Z-source topology and thus the photovoltaic energy is stored in a battery bank.

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.
