Comparative Study of Three level and Five level Inverter

Pallavi Appaso Arbune, Asha Gaikwad

This paper analyses and compares the different cascaded H-Bridge multilevel inverter used for dc to ac power conversion. The simulation of multilevel inverters is done in MATLAB/SIMULINK software.The activepoweroutput,reactive power output and Total Harmonic Distortion (THD) in output voltage produced in 3-level and 5-level inverters are obtained and compared.It was observed that THD in 5-level inverteris less as compared to 3- level inverter & THD in 7-level inverter is less as compared to 3-level and 5-level inverter.
