Abstract: This study proposes the implementation of Voltage Oriented Control (VOC) for three phase PWM rectifier. The basic principles of the PWM rectifier are analyzed and then the 3-phase mathematical of the input AC voltage sensorless PWM rectifier control system is established in synchronous rotating coordinates dq. The main goal of the control system is to maintain the dc output voltage at the desired value while input currents should be sinusoidal with minimum current harmonic and in phase whit respective phase voltages in order to satisfy the unity power factor operation. Moreover, a comprehensive comparison of the DC-bus voltage control will be undertaken between IP controller and fuzzy controller to obtain the active power control. A Dspace based experimental system was developed to verify the validity of the proposed VOC. Compared with IP controller fuzzy controller gives excellent performance intransient state, good rejection of impact load disturbance and a good robustness.
