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

open access: yes2014 14th Biennial Baltic Electronic Conference (BEC), 2014
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.
