Improved Symmetric Switched-Inductor/Capacitor Quasi Z-Source Inverter with Ability Uplifted-Boost [PDF]
International Journal of Industrial Electronics, Control and Optimization, 2020 This paper proposes a topology of switched-inductor/capacitor quasi z-source inverter (SIC-qZSI), which based on the classic qZSI. This topology is symmetric and has a high boost factor in the low duty cycle and high modulation index.
