The three phase quasi-switched boost inverter (qSBI) topology has one less LC pair than three phase Zsource/quasi-Z-source inverters. So, the qSBI is suitable for low-power applications. This paper presents a novel spacevector modulation (SVM) strategy for the three-phase qSBI topology to generate high-quality output waveforms with low THD of the output current and voltage. With introduced SVM strategy, according to sector number, the shootthrough phase is selected. Furthermore, the shoot-through state into the inverter’s switches and the switching-on state of an extra switch are controlled individually to boost the low input voltage up to a desired voltage level. Besides that, by using high modulation index, voltage stress across semiconductors and capacitor are significantly reduced. As a result, the inductor current ripple is reduced significantly. Simulation and experimental results of the qSBI with introduced SVM strategy are shown to verify the theoretical analysis.
