In order to improve the current performance of AC side for a three-phase PWM rectifier, this paper puts forward a current vector predictive control strategy. The discrete dynamic response of the current vector during the control period has been deduced through the discrete solving of Taylor series expansion and finite order truncation, so that the prediction of the current vector is achieved and testified by the relative distance. Then the discrete dynamical prediction control strategy of the current vector is proposed with the timings analysis to improve the rapidity and accuracy of the current vector tracking. Simulations and experiments are given to testify and verify the dynamic/steady-state performance and the efficiency of the control strategy, which can effectively improve the current vector tracking performance and reduce the harmonics and ripples.
