In this paper, a new structure for quasi-Z-source inverters based on the combination of switched inductors and transformers is proposed. In the proposed inverter, the high voltage gain is achieved by increasing the ratio of the transformer and the number of switched inductor cells. For proposed structure, the principles operation and calculations of voltage gains and average value of the voltage across the capacitors are provided. Power losses of the proposed structure are calculated and the efficiency comparison between the proposed and other structures is given. To determine the advantages and disadvantages of the proposed inverter, the comprehensive comparison between the proposed and conventional topologies is given. To prove the correctness operation of the proposed inverter, the simulation results in PSCAD/EMTDC are used.

Keywords: Z-Source Inverter, Quasi-Z-Source Inverter, Switched Inductors, Transformer, Shoot-Through
