An Energy-Stored Quasi-Z-Source Inverter for Application to Photovoltaic Power System
Baoming Ge,Haitham Abu-Rub,Fang Zheng Peng,Qin Lei,A.T. de Almeida,Fernando J. T. E. Ferreira,Dongsen Sun,Yushan Liu +7 more
TL;DR: Two strategies are proposed with the related design principles to control the new energy-stored qZSI when applied to the PV power system and prove the effectiveness of the proposed control of the inverter's input and output powers and battery power regardless of the charging or discharging situation.
Journal ArticleDOI
Modeling, Impedance Design, and Efficiency Analysis of Quasi- $Z$ Source Module in Cascaded Multilevel Photovoltaic Power System
Dongsen Sun,Baoming Ge,Baoming Ge,Xingyu Yan,Xingyu Yan,Daqiang Bi,Hao Zhang,Yushan Liu,Haitham Abu-Rub,Lazhar Ben-Brahim,Fang Zheng Peng +10 more
TL;DR: An analytic model to accurately calculate the 2ω voltage and current ripples of each qZSI module and the power loss is proposed and the measured efficiency from the prototype verifies the theoretical calculation, and the qZS-CMI-based grid-tie PV power system is tested in practical.
Journal ArticleDOI
Overview of Space Vector Modulations for Three-Phase Z-Source/Quasi-Z-Source Inverters
TL;DR: In this paper, three existing and one extended space vector modulations (SVMs) for the three-phase Z-source/quasi-Z-source inverter (ZSI/qZSI) are investigated.
Journal ArticleDOI
