Design and simulation of PV fed Multi-Level Inverter (MLI) through the DC-DC converter in Continuous Conduction Mode (CCM) have been carried out in this work. The voltage regulated PV fed DC-DC power converter is used as DC source for the MLI . Multicarrier PWM switching strategies are used for the selected seven level asymmetric MLI. The mathematical model of PV system and DC-DC converter have been presented and verified under varying climatic and load conditions. To improve the performance of the PV system, PI controller PWM control scheme and on-line INC MPPT algorithm with fixed and variable step size has been developed. Simulations are carried out using MATLAB/SIMULINK Simpower System block set .In variable step size MPPT method the PI controller modifies the step size enabling faster tracking of the maximum input power and shows the improvement in the efficiency of energy utilization. The developed setup is fed to the two H-Bridge cascaded asymmetric MLI to generate 7-level sinusoidal AC output .
