Pulse width modulation (PWM) is a widely used technique in power electronics to control the output voltage and frequency of inverters. Sinusoidal PWM (SPWM) is a common method in which the switching signals are generated by comparing a sinusoidal reference waveform with a high-frequency triangular carrier. This study presents the simulation of sinusoidal PWM signals using MATLAB/Simulink and SCILAB. The study involves generating the SPWM signals, analyzing their waveform characteristics, and evaluating their effectiveness for controlling inverter output. The simulation results demonstrate the ability of the SPWM technique to produce a high-quality AC waveform with reduced harmonic distortion. Comparative analysis between MATLAB/Simulink and SCILAB tools is also discussed to highlight their suitability for PWM waveform generation and control applications. The findings confirm that both software environments provide effective means for modeling, simulation, and analysis of PWM techniques in power electronic converters.
