Abstract :
In recent years, space vector pulse-width modulation (SVPWM) technique obtains widespread application in AC modulation because of its high utilization of dc bus, fast dynamic response and easier digital realization. The paper focuses on the bi-dirction control methodology based on a 50 kW three-phase AC-DC PWM rectifier of high power factor. Active and reactive current are controlled respectively in d-q rotating coordinatce system and unity power factor rectifier can be achieved. First SVPWM control principle is analyzed and the control schematic of the entire system is provided. Next simulation model of SVPWM is obtained using MATLAB/SIMULINK. Finally simulation results are also provided.
