Focus of this study is on a new switched-capacitor current-fed (CF) quasi-Z-source inverter (qZSI) topology, which is derived from the conventional CF qZSI. Each capacitor of quasi-Z-source network is replaced by switching-capacitor cell built with two capacitors and three diodes. As shows performed steady state analysis of idealized converter the proposed CF qZSI offers extended regulation region and increased voltage gain. Bi-directional power transfer and wide regulation range fit requirements of electric vehicle applications. Operation modes have been verified by numerical simulation in PSIM.
