System simulation of 3-phase PWM rectifier based on novel voltage space vector

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.
