摘　　要：首先分析了三相电压型PWM整流器的拓扑结构和数学模型,然后对基于瞬时功率估算的直接功率控制、电压定向的直接功率控制、无电压传感器虚拟磁链的直接功率控制、基于定频的虚拟磁链和变换器输出电压计算的直接功率控制进行性能分析,比较其各自的优缺点。并在此基础上对三相电压型PWM整流器直接功率控制策略进行了展望。The topology and mathematical model of three-phase voltage source PWM rectifier was analyzed in this paper. Then, the direct power control based on instantaneous power estimation, direct power control without voltage sensor, virtual flux based on fixed frequency and converter output voltage calculation were analyzed, and their advantages and disadvantages were compared. On the basis of current research, the direct power control of three-phase voltage source PWM rectifier was prospected.
