Trans-Z-Source Inverters

IEEE Transactions on Power Electronics, 2010
This paper extends the impedance-source (Z-source) inverters concept to the transformer-based Z-source (trans-Z-source) inverters. The original Z-source inverter (ZSI) employs an impedance network of two inductors and two capacitors connected in a special arrangement to interface the dc source and the inverter bridge.

Z-Source Inverter Based on CUK Converter

IECON 2018 - 44th Annual Conference of the IEEE Industrial Electronics Society, 2018
This paper proposes a new three-switch single-phase Z-source inverter (ZSI) based on CUK converter, which is named CUK-based ZSI. This topology has the characteristics of buck-boost capability and dual grounding. In addition, the voltage gain of proposed inverter is higher than those of the single-phase quasi-Z-source and semi-Z-source inverters. Aside

Sigma‐Z‐source inverters [PDF]

IET Power Electronics, 2015
To increase the boost capability with minimum passive components, existing transformer‐based Z‐source inverter (ZSI) topologies require the turn ratio to be increased. This results in larger transformer windings to be used in high dc–ac voltage gain applications.
