As conventional two level inverter has limited power handling capability and high harmonic distortion in the output voltage, Multilevel inverter concept is growing as the new class of power converters for high and medium power applications. Multilevel inverters synthesize a near sinusoidal voltage from several levels of dc voltages with has minimum harmonic distortion. In present days, for control of multilevel inverters, Carrier Based Pulse Width Modulation (CBPWM) techniques gained importance because of simplicity in expansion to higher levels and can be applied to Sinusoidal and Space Vector modulation schemes. This paper discusses about adoption of Carrier Based Sinusoidal Modulation technique for 3 and 5 Level Flying Capacitor Multi Level Inverter(FCMLI). A comparative study of the performance of Three and Five level FCMLI is presented in terms of THD in the inverter voltage. Simulations are carried out using MATLAB/SIMULINK to validate effective suppression of harmonics when higher level inverter is adopted.
