Switched capacitor based Z‐source DC–DC converter [PDF]

IET Power Electronics, 2019
This study proposes a common grounded Z‐source DC–DC converter. In comparison to conventional Z‐source converter, it converts voltage with higher voltage gain and lower voltage stress on the switch, diodes and capacitors. In addition, it needs smaller inductors in comparison to the similar converters.

Z‐source‐based isolated high step‐up converter

IET Power Electronics, 2013
Continuous input currents and high step‐up ratios are desired from the dc–dc converters that work with renewable energy sources such as photovoltaic panels and fuel cells. Most dc–dc converters use transformers to have high step‐up ratios. There is another type of converters that use coupled inductors, but they need to operate at high duty cycles to ...

Voltage and Current Programmed Modes in Control of the Z-Source Converter

2008 IEEE Industry Applications Society Annual Meeting, 2008
The Z-source converter (ZSC) is an alternative power conversion topology that can both buck and boost the input voltage using passive components with improved reliability. Dynamic modeling of the ZSC from different perspectives has been studied. So far, based on these models, the dc-link voltage is controlled using direct measurement, or through ...

Switched Z-Source/Quasi-Z-Source DC-DC Converters With Reduced Passive Components for Photovoltaic Systems [PDF]

IEEE Access, 2019
In this paper, switched Z-source/quasi-Z-source dc-dc converters (SZSC/SQZSCs) are proposed for the photovoltaic (PV) grid-connected power system, where the high step-up dc-dc converters are required to boost the low voltage to high voltage. The boost factor is increased by adding another one switch and diode to the output terminals of traditional Z ...

Extended family of DC-DC Quasi-Z-Source converters

International Journal of Electrical and Computer Engineering (IJECE), 2019
The family of DC-DC q-ZSCs is extended from two to three classes and four to six members. All the members were analyzed based on efficient duty ratio range (R_Deff) and general duty ratio range (R_Dgen). Findings showed that similar to the traditional buck-boost converter (BBC), each of the topologies is ...

A quasi-Z-source boost DC-DC converter

Gong-kuang zidonghua, 2017
For problems of traditional boost converter including limited boost ability and high capacitor voltage stress, a boost DC-DC converter was proposed which used two quasi-Z-source networks in cascade. Working process of the converter was analyzed, and expressions of step-up ratio and capacitor voltage stress were derived.
