Pulse width modulation (PWM) converters are frequently used due to unity power factor operation with reduced total harmonic distortion (THD) at ac mains and also provide constant-regulated dc output voltage even under fluctuations of ac voltage and dc load. This paper contains the harmonics analysis of sinusoidal PWM (SPWM) technique and space vector PWM (SVPWM) technique for three-phase AC to DC converters using MATLAB/SIMULINK software. In this paper simulation models for both techniques are simulated with closed loop at rated load condition and harmonics analysis has been done using FFT tool of simulink in MATLAB.
