<abstract>In this paper, a new multilevel converter which consists of only the seven switches rather than the conventional multilevel converter is analyzed. The various PWM techniques were included: APODPWM, COPWM and PSPWM, to generate the respective output voltage levels. It has many main advantages of lower harmonics, reductions in installation space and cost of inverter. The performance measures like Total Harmonic Distortion (THD), VRMS (fundamental) and V are peak evaluated for various modulation indices. This proposed multilevel converter can be analyzed and investigated through MATLAB/SIMULINK software. Finally, compared with all PWM strategies, the COPWM and PSPWM provide higher (fundamental) RMS voltage and APODPWM provides lower Total Harmonic Distortion (THD).</abstract>
