【Abstract】 The mathematical model of three-phase PWM rectifier is set up at first in this paper, and then the vector control strategy is analyzed in detail. A simple algorithm is proposed based on voltage space vector, which directly calculates the duration of voltage space vector in each sector according to the reference voltage vector in reference frame. At last, experimental results verified the proposed scheme.更多还原
