Abstract: This paper is focused on the development of the rectifier for three phase voltage source to achieve unity power factor at input supply mains. The mathematical model is developed for PWM using direct current control and to apply 3-phase voltage source rectifier decoupled with feed-forward control. This method regulates the output voltage with reduced harmonics. Different PWM techniques such as Hysteresis band and Carrier based sinusoidal is applied and their performance is analysed. This work is implemented in MATLAB/SIMULINK environment. The results confirm the validity of the model and its control method.
Keywords: PWM rectifier, Direct Current Control (DCC), Hysteresis-band PWM, Carrier-based sinusoidal PWM, Space vector PWM.
