Abstract :

The cascaded multilevel inverter (CMLI) has gained much attention in recent years due to its advantages in high voltage and high power with low harmonics applications. A standard cascaded multilevel inverter requires n DC sources for 2n+1levels at the output, where �n� is the number of inverter stages. This project presents a topology to control cascaded multilevel inverter that is implemented with multiple DC sources to get 2n+1–1 levels. Without using Pulse Width Modulation (PWM) technique, the firing circuit can be implemented using Microcontroller which greatly reduces the Total Harmonic Distortion (THD) and switching losses. The model of a cascaded hyid multilevel inverter is developed with software simulation using MATLAB/SIMULINK software.
