In this paper, three phase Vienna rectifier (VR) topology with sinusoidal input currents and controlled output voltage has been derived with various PWM switching techniques. A comparative study of four different PWM switching techniques for the best performance of Vienna rectifier is presented here using simulink model. Sinusoidal PWM, Trapezoidal PWM, Space vector PWM and PWM using Hysteresis method are presented here. Vienna rectifier performance like Total Harmonics Distortion (THD) and Power factor (PF) along with various Load conditions and switching condition were observed. We have tried to suggest which PWM is better among them to improve performance of Vienna rectifier
