CCM and DCM Analysis of quasi-Z-Source Inverter
2018This paper presents an analysis of a quasi-Z-source inverter (qZSI) operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). The boundary between CCM and DCM is discovered and technique to avoid qZSI being operated in DCM is also discovered.

Switched-Coupled-Inductor Quasi-Z-Source Inverter
IEEE Transactions on Power Electronics, 2016Z-source inverters have become a research hotspot because of their single-stage buckâboost inversion ability, and better immunity to EMI noises. However, their boost gains are limited, because of higher component-voltage stresses and poor output power quality, which results from the tradeoff between the shoot-through interval and the modulation index ...

Novel Space Vector Modulation Method for the Quasi-Z-Source Asymmetrical Three-Level Inverter
IEEE Transactions on Circuits and Systems - II - Express BriefsThe quasi-Z-source (QZS) asymmetrical three-level inverter (ATLI) can be regarded a post-fault topology of the QZS T-type three-level inverter. Due to the inherent limitation of this topology, the output states are restricted, and the conventional ...

Constraints and control strategies of quasi-Z-source cascaded multilevel inverter
IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017The quasi-Z-source cascaded multilevel inverter is a new type of inverter topology that can achieve buck/boost and DC-AC conversion in single-stage system and output multi-level voltage. When it is applied to distributed grid-connected generation, a big output power difference between modules will lead to grid-connected current distortion and system ...

Enhanced Boost Active Switched Impedance Quasi Z-Source Inverter
2019 International Conference on Electrical Engineering and Informatics (ICEEI), 2019A new topology called Enhanced Boost Active Switched Impedance-qZSI (EBASZ-QZSI) was introduced in this paper. This topology has a high voltage gain value with a smaller duty cycle compared to the previous topology. This topology also offers lower current ripple values and voltage stresses compared to the previous topology under the same conditions ...
