Quasi‐Z‐source inverter with switched‐coupled‐capacitors
This paper presents an improved switched‐inductor quasi‐Z‐source inverter with a higher boost factor than similar inverters, which integrates a switched‐capacitor and a three‐winding switched‐coupled inductor into a conventional quasi Z‐source inverter ...

A Switched Quasi-Z-Source Inverter with Continuous Input Currents [PDF]
Impedance source converters as single-stage power conversion alternatives can boost and regulate the output voltages of renewable energy sources. Nevertheless, they, also known as Z-source inverters (ZSIs), still suffer from limited voltage gains and ...

Switched-Inductor Quasi-Z-Source Inverter
This paper deals with a new family of high boost voltage inverters called switched-inductor quasi-Z-source inverters (SL-qZSIs). The proposed SL-qZSI is based on the well-known qZSI topology and adds only one inductor and three diodes. In comparison to the SL-ZSI, for the same input and output voltages, the proposed SL-qZSI provides continuous input ...

A wavelet modulation method for a quasi-Z-source inverter
A wavelet modulation strategy applied to a quasi-Z-source inverter was proposed. The regulating range of the shootthrough duty ratio could be increased by changing the locations of the sampling points set using traditional wavelet-modulation.

Maximum Boost Control Method for Single-Phase Quasi-Switched-Boost and Quasi-Z-Source Inverters
The maximum boost control method for a single-phase switched-boost inverter (SBI) and single-phase Z-source inverter (ZSI) is proposed in this paper. In the proposed method, the low frequency voltage is added to the constant voltage for generating the ...

Sliding Mode Control for Three-Phase Quasi-Z-Source Inverter
In this paper, a novel multiobjective control strategy for the three-phase quasi Z-source inverter (q-ZSI) is proposed. A sliding mode control (SMC)-based controller is proposed to regulate inductor current through shoot-through ratio, and DC-link ...
