Abstract


This paper presents the performance evaluation of Stepped DC link Quasi Z source inverter with different modulation techniques. The proposed stepped DC link quasi Z source inverter integrates the stepped DC link circuit with the Z source inverter to yield multilevel AC voltage. This improves the quality of the output voltage and stepped DC input reduces the inrush current and minimizes the losses. The performance of the inverter varies for different modulation strategy. Hence the performance of the proposed inverter is evaluated with different modulation techniques to identify the effective modulation strategy. The circuit is simulated in MATLAB/Simulink to make a detailed study on the effect of control technique and the results are presented.
