Z-Source Cascaded Multilevel Inverter Fed IM for Selective Harmonic Minimization & THD Reduction with PV Cell Input

A. Pradeep Kumar; B. Vamsikrishna

Abstract: This paper deals with a new hybrid multilevel inverter with Z-source converter fed induction motor drive which focuses. This paper approximates the reduction of total harmonic distortion and selective harmonic minimization using new model asymmetric cascaded multilevel inverter by PWM technique using MATLAB/SIMULINK. The switching angles are mathematically calculated. This method provides a lower total harmonic distortion and lower order harmonics are minimized drastically.6 level inverter input for the inverter is boosted using Z-source converter & the input for converter is from PV.
