The quasi-switched-boost inverter is an alternative to the quasi-Z-Source inverter. Its passive component number is two times smaller but it contains two additional semiconductor components. Earlier the switched-inductor cell was applied in this topology to enhance dc voltage gain at the cost of high input current ripple. This paper proposes a novel switched-inductor quasi-switched-boost inverter topology with low input current ripple and enhanced dc voltage gain. It is based on a modified switched-inductor cell where the input source is connected in series with an inductor. Operation principle is described through separation of the switching period into three intervals. Equivalent circuits and circuit equations are shown for each interval. Simulation study corroborates theoretical predictions.
