Feasibility Study of Interleaving Approach for Quasi-Z-Source Inverter

This paper presents a comprehensive feasibility study of an interleaving approach for a quasi-Z-source inverter. The state-of-the-art approach revealed that an interleaving approach is often used to improve the efficiency and power density that can overcome the problem of oversized passive elements...
