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 charachterestics, 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.

“…The conventional ZSI demonstrated the step up/step down conversion in single stage along with EMI immunity and zero dead time operation [5] [6]. However, conventional ZSI has high start up current, discontinuous input current, high voltage stress and absence of common ground [7], [8], [9]. The conventional quasi Z-source inverter (QZSI) is advanced version of ZSI, which provides continuous input current, lower voltage stress and common ground while preserving the boost factor similar to ZSI [10].…”

“…To increase the voltage gain, several topologies are reported [10], [12], [13] which are derived from QZSI such as switched inductor QZSI [14], quasi switched boost inverter [15] etc. However, few of these topologies can have chopped input current [16], [8], [17] and lack of common ground…”

The motivation of this paper is to bring into notice the establishment of two topologies: enhanced boost-quasi Z source inverter (EB-QZSI) and enhanced boost QZSI with an active switched network (EB/ASN-QZSI) which have poor performance than Extended switched capacitor quasi switched boost inverter (ESC-qSBI). However, ESC-qSBI has been developed before the EB-QZSI and EB/ASN-QZSI. The ESC-qSBI utilizes lesser number of inductors than the enhanced boost-quasi Z source inverter (EB-QZSI) and enhanced boost QZSI with an active switched network (EB/ASN-QZSI). In the presence of parasitics, ESC-qSBI has higher voltage gain than the EB-QZSI and EB/ASN-QZSI. Additionally, EB/ASC-QZSI has lower total voltage stress across diodes and capacitors as compared to EB-QZSI and EB/ASN-QZSI. The operation, steady state analysis, comparison and experimental analysis are discussed to prove the superorrity of ESC-qSBI over EB-QZSI and EB/ASN-QZSI.
