Abstract: This paper presents a topology with a reduced number of switches, which is used to reduce the total harmonic distortion (THD %) using MCPWM technique, MCPWM with trapezoidal reference wave and also SHE technique such as PSO technique and Newton-Raphson (NR) technique. SHE technique is used to eliminate a particular harmonic in a multilevel inverter (MLI), the MCPWM and Trapezoidal reference wave techniques are also used to reduce the harmonics present in the MLI with a triangular wave which acts as a carrier wave. This topology is also used to improve the multilevel performance. The performance evaluation of the proposed PWM, Trapezoidal reference wave and SHE techniques for a MLI is done by using MATLAB/Simulink and THD is analysed. It is observed that PSO technique produces a better fundamental voltage output and less THD.
