Control Strategy For Three Phase Pwm Rectifier Using Svm Modulation

Transcript

This paper deals with the control of three phase PWM rectifier model using SVM based current controller. In many power electronics control applications the rectifier plays vital role during AC/DC power conversion. The SVM-based HCC scheme is simulated using MATLAB simulink. The technique combines the best features of the SVM and HCC techniques. The controller determines a set of state space vectors from a region detector and then applies a space vector selected according to HCC. A set of space vectors in a region, including the zero space vector for a reduced number of switching, is determined from the output signals of three comparators with a hysteresis band a little larger than that of the main HCC. The Simulation results prove the effectiveness of the proposed three phase PWM rectifier model.
