N2 - Inverters have become popularly used in the field of Power Electronics for different applications. Inverters having harmonics existence in the output voltage have led to many research works being conducted. Different topologies were applied to mitigate this inverter drawback, thus improving the efficiency of the inverter. Sinusoidal Pulse Width Modulation (SPWM), Hysteresis Band Current Controller Pulse Width Modulation (HCCPWM) and Modified Sinusoidal Pulse Width Modulation (MSPWM) techniques have been discussed and implemented in Matlab/Simulink software. Full-bridge single phase topology is used. Simulations results are presented. Modulation index and number of pulses are only two usual parameters used in these three modulation techniques. Minimum Total Harmonic Distortion (THD) is applied as a benchmark key performance indicator (KPI) in comparing the output results generated from all the techniques investigated and verified. The results show that Modified Sinusoidal PWM technique produce better results as compared to SPWM and HCCPWM techniques. The results generated from MSPWM technique have reduced harmonics and the output voltage is more sinusoidal without the use of an ideal switching technique. This paper demonstrated the output voltage performance relation between SPWM, HCC and MSPWM carried-out in the unipolar inverter.
