System Simulation of 3-phase PWM Rectifier Based on Novel Voltage Space Vector

ABSTRACT:

A novel voltage space vector control method based on Hysteresis Current Control is proposed. This method gives the optimal space vector by detecting the current error space vector and the system reference voltage space vector, and then controls the current error below the hysteresis width. Voltage space vector is introduced into the control system to eliminate the phase interference, and it can be realized simply without complicated vector transform. The proposed method has fast current response, and can limit the current error and the switching frequency with good current tracking performance. The system Mathematical mode is set up in this paper. The validity of the mathematical model and its control method are confirmed by MAT-LAB/SIMULINK simulation.

CONCLUSION:

In this paper a novel SVM-Based Hysteresis Current Control for 3-phase PWM VSR is suggested, which utilizes all advantages of the HCC and SVM technique. This method gives the optimal space vector by detecting the current error space vector and the system reference voltage space vector, and then controls the current error below the hysteresis width. The method can reduce the switching frequency, and has good current tracking performance. The validity of the mathematical model and its control method are confirmed by MAT-LAB/SIMULINK simulation.
