Switched Inductor Z-source/quasi Z-source Network: State of Art and Challenges

In recent years, the impedance source network has been studied by many researchers focusing on high conversion gain power electronics. Several number of topologies have been developed. The combination of the Switched inductor cells and Z-source networks has shown its capability of achieving high voltage gains and good power conversion at low shoot through duty cycle values as compared to traditional Z-source network. This paper contributes as an overview of different Switched inductors cells combined with Z-source or quasi Z-source network. General analytical classification, main characterestics, and comparison of different topologies and their modifications, are provided in this paper. This study should be of interest for engineers and researchers when selecting their high voltage gain impedance source converter.
