A novel Z-source dc-dc converter
2008 IEEE International Conference on Industrial Technology, 2008This paper proposes a novel Z-source dc-dc converter topology. Compared to the existing dc-dc converter circuits, they can reduce in-rush and harmonic current, provide larger range of output dc voltage and improve reliability. It can operate in voltage-fed and current-fed when the place of the source and load is exchanged each other, and it can be ...

When realized as a dc-dc converter, the introduced Z-source impedance network must similarly be short-circuited for a certain defined duty ratio per switching period. The basic operating principles therefore remain unchanged, except that the rear-end converter bridge is changed to one suitable for performing dc-dc conversion.

The Design of Quasi-Z-Source Boost Converter
Applied Mechanics and Materials, 2014According to analyzing the basic principle of intrinsically safe output quasi-Z-source Boost Converter, this topology can be modeled. When the quasi-Z-source network parameters Lz and Cz are much smaller than conventional converter parameter LC, transfer function can be order-reduced.

Modeling of Z-source converter for renewable energy integration
2013 North American Power Symposium (NAPS), 2013In this paper, switching modulation schemes for Z-source converters used for renewable energy integration are investigated. Both dc-dc converters and dc-ac converters are discussed. Input/output voltage relationships for the two types of converters (half-bridge dc-dc and three-phase three-bridge dc-ac) are analyzed based on circuit analysis.

Double input Z-source DC-DC converter
2011 2nd Power Electronics, Drive Systems and Technologies Conference, 2011This paper proposes a double input dc-dc converter based on Z-source converters. In the proposed converter, the input dc voltage can be boosted and also input dc sources can deliver power to the load individually or simultaneously, so combination of a battery with one of the new energy sources such as solar array, wind turbine or fuel cell can be used ...

Control and modulation techniques of Z-source converter
This chapter presents an overview of control and modulation techniques for Z-source converters (ZSCs) used for electric power conversion. ZSCs are categorized into four main categories: DC/DC converters, DC/AC inverters, AC/AC converters, and AC/DC rectifiers.Ping Liu +3 more
