摘　　要：建立了三相电压型PWM整流器的数学模型,并对其矢量控制策略进行了分析,采用输入电压空间矢量定向,根据参考指令电压矢量直接计算空间电压矢量位置和作用时间,结合直接电流控制的方法进行电流跟踪控制,仿真结果证明了该方案的有效性。The mathematical model of three-phase PWM rectifier is set up in this paper,and then the vector control strategy is analyzed in detail.It calculates the position and operation time of the voltage space vector directly with the input voltage space vector orientation and according to reference voltage vector.Using a direct current control method to trace current signal,the simulation results verified the validity of the proposed scheme.
