Hybrid Z-Source Boost DC–DC Converters
IEEE Transactions on Industrial Electronics, 2017This paper presents a new family of hybrid Z-source boost dc–dc converters intended for photovoltaic applications, where the high step-up dc–dc converters are demanded to boost the low-source voltages to a predefined grid voltage. Because the boost capabilities of the traditional Z-source networks are limited, the proposed converters are composed of ...

A common grounded Z-source buck-boost converter
2011 IEEE International Symposium of Circuits and Systems (ISCAS), 2011A novel circuit topology of the Z-source dc/dc converter, ‘Common grounded Z-source buck-boost converter’ is proposed. The proposed converter realizes the buck gain in addition to the boost gain in the positive output voltage range, which was only realized in the negative output voltage range in the previous research. Furthermore, the proposed topology

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.

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.

Bidirectional cascaded quasi-Z-source DC-DC converter
IECON 2014 - 40th Annual Conference of the IEEE Industrial Electronics Society, 2014This paper proposes bidirectional cascaded quasi-Z-source dc-dc converter (BC-qZSC). Compared to the traditional cascaded quasi-Z-source network (C-qZSN), the diodes in C-qZSN are replaced by active switches with a parallel diode. BC-qZSC has the higher boost ability and the lower input current ripple than those of the bidirectional quasi-Z-source dc ...

A Comparative Study of Series and Cascaded Z-Source Matrix Converters
IEEE Transactions on Industrial Electronics, 2014The series Z-source network, an expansion of the popular concept of the Z-source dc link, was originally proposed for boosting the output voltage of power electronic inverters. In this paper, that idea is extended on a three-phase indirect matrix converter. The converter is based on the ultrasparse matrix topology characterized by the minimum number of

Grid connected quasi-Z-Source direct matrix converter
IECON 2013 - 39th Annual Conference of the IEEE Industrial Electronics Society, 2013This paper proposes a new three-phase ac-ac converter topology based on the Z-source concept and the conventional direct matrix converter (DMC), it is called quasi-Z-Source direct matrix converter (QZSDMC). It could provide buck-boost function and make the role of frequency changer.

Trans-Z-source-based isolated DC-DC converters
2013 IEEE International Symposium on Industrial Electronics, 2013The new isolated step-up dc-dc converters based on the trans-Z-source/-quasi-Z-source networks are proposed in this paper. By adjusting the shoot-through duty cycle and changing the transformer turn ratio of the trans-Z-source network, the proposed trans-Z-source-based dc-dc converters have a lower shoot-through duty cycle compared to the conventional ...
