Quasi-Impedance Source Inverters

In recent years, many researchers have worked in many directions to develop impedance source inverters (ZSIs) to achieve different objectives [1,2,3,4,5,6,7,8]. Some have worked on developing different kinds of topological variations, whereas others have worked on developing ZSI into different applications where controller design, modeling and analyzing its operating modes, and developing modulation methods are addressed. Theoretically, ZSI can produce infinite gain like many other DC/DC boosting topologies; however, it is well known that this cannot be achieved due to effects of parasitic components where the gain tends to drop drastically [1]. Conversely, high boost could increase power losses and instability. ...
