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
