Abstract

This paper presents a review in terms of new configurations involving the Z-source converter concept. Since its first appearance, it is evident the importance assumed by the Z-source converter in the last years as a new topological structure with interesting features. As far as the authors’ interest regarding the Z-source converter increases, new topologies have been developed for different applications. In spite of that, it is not observed in technical literature any reference furnishing a compilation of themain configurations related to this topic. The goal of this paper is to provide a complete range on the status of the Z-source converter topologies to professionals and researchers interested in this topic. The configurations are grouped in five categories: (i) twolevel configuration, (ii) multilevel configuration, (iii) Zsource network improvement, (iv) ac-ac conversion, and (v) matrix converter. Based on the paper organization, it is possible to trace objectively the main developments in terms of new Z- source converter topologies.
