A novel space vector hysteresis control for three-phase voltage source PWM rectifier
The improved space vector hysteresis control was introduced for the disadvantage of poor current tracking caused by the traditional control strategy in the three-phase voltage source PWM rectifier. The improved strategy choose the hysteresis loop width and the switch state through the judgment of the AC error current vector modulus, and the selection principle of the switch state was provided in order to reduce the switching losses. Final y, the simulation model was established under matlab/simulink to compare AC current quality between the traditional and the improved control strategies, the simulation results further demonstrated the superiority of the improved control scheme.
