Comparative Evaluation of Generalized Multicell Impedance Source Inverter for Drives
International Journal of Power Electronics and Drive Systems (IJPEDS), 2014 Voltage-Source Inverter is limited by its only voltage step-down operation. In adding with extra boosting the flexibility is kept active for the number of semiconductors which is unchanged, voltage-type Z-source inverter was earlier proposed. These new classes of inverter is generally less sensitive to electromagnetic noises.
