Abstract : Multilevel inverter has benefits like low stress on switches, low harmonic distortion and can be used in high voltage and high power applications. In this paper 7 - level Multilevel inverter which has less number of switches is considered with various PWM Techniques. The different PWM techniques considered are Carrier-Overlap PWM(CO-PWM), Variable Frequency PWM(VF-PWM), Phase Shifted PWM(PS-PWM), Alternate Phase Opposition Disposition PWM(APOD-PWM), Phase Disposition PWM(PD-PWM), Phase Opposition Disposition PWM(POD-PWM). The given topology is modeled and simulated with the help of MATLAB/SIMULINK to check which PWM technique leads low THD value.
