Current-fed quasi-Z-source inverter-based adjustable speed drive system(ASDs)

Current-fed quasi-Z-source inverter (qZSI) has many advantages over traditional current source inverter and current-fed Z-source inverter. This paper presents and analyzes the novel adjustable speed drive system (ASDs) based on the current-fed quasi-Z-source inverter, includes its topology, operating principle, voltage gain. The simulation results are given to verify the rationality and feasibility of the proposed topology.
