Abstract
|
This study reviews and categorises different structures of switched Z-source networks. Generally, these structures are divided into two groups of basic switched Z-source networks and switched Z-source networks with the capability of high boost. Each of these groups is divided into several subgroups and different structures are introduced. For each subsection, the general power circuit is proposed and the extraction method from general power circuit for each structure is obtained. This study also provides a complete analysis of structures by using a conventional control method with two shoot-through and non-shootthrough modes. Small signal analysis for structures with a basic switched Z-source network is conducted and the general signal flow graph is extracted. A comprehensive analysis of all structures with a switched Z-source network is done and the tree diagram for the division of these structures is provided. Finally, different industrial applications and outlook of Z-source networks are introduced.
