Switched-Inductor Quasi-Z-Source Inverter
IEEE Transactions on Power Electronics, 2011 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 ...

Novel Switched-Inductor Quasi-Z-source Inverter [PDF]
Journal of Power Electronics, 2014 A novel switched-inductor quasi-Z-source inverter is proposed in this study. Compared with classic topologies, the boost ability of the proposed topology is strengthened. The voltage stress of the capacitors, diodes, and power devices are reduced, and the current ripple of the DC voltage source is suppressed. Conversion efficiency is also improved. The
