Switched Z‐source networks: a review [PDF]
IET Power Electronics, 2019 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.
