摘　　要：本文介绍了一种改进的基于虚拟磁链定向三相PWM整流器。提出了一种没有直流偏移的虚拟磁链定向观测器,并将其与传统的虚拟磁链定向观测器作了比较,得出其响应的稳定性、准确性和快速性。最后在Matlab/Simulink中搭建了改进的三相PWM整流器的仿真,并将仿真与dSPACE实验平台连接观察并分析,验证了所提出的基于虚拟磁链定向三相PWM整流器的可行性。This paper introduces the control method of three-phase PWM rectifier based on virtual flux oriented. A virtual flux observer without DC drift is proposed, and compared with the traditional virtual flux observer, reflecting the stability accuracy and rapidity of response. Finally, the simulation of three-phase PWM rectifier builted in Matlab/Simulink, and connected to dsPACE to observe and analysis, the feasibility of three-phase PWM rectifier Based on Virtual Flux Oriented is verified.
