“…This classification based on the above modifications is termed as single‐phase alternative SBI structures in this paper herewith. The categorization of single‐phase alternative SBI topologies is shown in Figure 3, leading to improved SBI [37], CFSI [38], trans‐SBI [41], SLBI [42], SBI with four switches [72] etc. These alternative structures are derived by rearranging the components of basic SBI.…”

Single-stage switched boost inverter (SBI) with buck-boost capability finds wide applications in renewable energy systems (RES). This paper aims at a comprehensive topological review of various single stage SBI circuits. The boosting techniques of SBI include switched inductor, switched capacitor, and transformer assisted switches. Each SBI derived structure has its own merits and demerits depending on the applications. The performance evaluation of SBIs, based on various perspectives like boost factor, voltage stress across active devices, passive elements count, DC link voltage, switching losses, voltage gain, and efficiency, are also discussed. A suitable modulation strategy is used to obtain the desired boosted and inverted ac output voltage in one stage SBI. Different modulation strategies adopted for SBIs are also included at the end of the topological review. This topological review's contribution enlightens the researchers in selecting appropriate SBI with effective modulation strategies suitable for renewable energy applications. Besides, the benefits and shortcomings of these converters are discussed in detail.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…In order to decrease the voltage stress across the capacitors in the conventional Zsource network, series ZSI has been presented in [37]. All of the structures that have been presented in [25][26][27][28][29][30][31][32][33][34][35][36] are the switched boost inverters with a voltage source. In [33,34], the dual of these structures with the current source has been presented and they increase the current level and are immune from an open circuit.…”

“…Like SBI, these structures are able to supply both ac and dc loads simultaneously but the voltage stress of the capacitors in higher duty cycles is more than the other structures. In order to decrease the voltage stress on the capacitor, in [35, 36], quasi‐switched‐boost inverter (qSBI) has been presented. The Z‐source network of qSBI is in series with the input voltage source, which leads to a decrease in voltage stress on the capacitor, but the voltage boost factor is equal to the boost factor of the SBI.…”

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.
