A Modified Switched-Coupled-Inductor quasi-Z-source Inverter

This article proposes a modified switched-coupled-inductor quasi-Z-source inverter, which is characterized by a continuous input current, low dc-link voltage overshoot, and high efficiency. The bootstrap capacitor in this improved module enhances the boost capability of the inverter at a low shoot-through duty cycle $D$ . Thanks to the distinct positions of the third and fourth windings $N_{23}$...
