Three-phase three-level voltage source inverter construction based on quasi-Z-source cells

This article describes the features of construction and operation of three-phase three-level voltage source inverter (qZSI) with quasi-Z-source cells. The topology and the control method were proposed. The equations for calculating the parameters of a quasi-Z-source cell were obtained in general form. The simulating of the proposed converter was conducted. The simulation results confirmed the efficiency of the proposed topology.
