A Modified Two Switched-Inductor QUASI Z-Source Inverter

In this paper, the technique of bootstrap capacitor is applied to the (cSL-qZSI) topology to improve its features such as increasing its total gain and minimizing the total stress across the used component Using switched inductor principle has improved the boosting gain of the applied topology at the same shoot through duty cycle (D) compared with the convention one. This also leads to operate at higher modulation index (M) and so low stress over the components is resulted. Switched inductor cell is applied to classic qZSI topology instead of the two main inductors to give anew topology that has been called a continuous input current switched inductor quasi Z-Source Inverter (cSL-qZSI)
