Switched-capacitor current-fed quasi-Z-source inverter

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 the quasi-Z-source network is replaced by a switching-capacitor cell built with two capacitors and three diodes. As our steady state analysis of an idealized converter shows, the proposed CF qZSI offers an extended regulation region and increased voltage gain. Bi-directional power transfer and a wide regulation range fit the requirements set for electric vehicle applications. Operation modes were verified by numerical simulation in PSIM.
