摘　　要：针对采用定基本空间矢量-空间矢量脉宽调制控制的三相维也纳(Vienna)整流器在抑制直流侧电压波动方面存在缺陷的问题,提出一种变基本空间矢量-空间矢量脉宽调制(variable basic space vector-space vector pulse width modulation, VBSV-SVPWM)控制。将直流侧实时电压反馈回控制电路,构成VBSV-SVPWM控制,使得系统对于直流侧电压波动有着更好的响应性能。在MATLAB/Simulink中搭建仿真模型,验证所述理论的正确性。试验结果表明,采用VBSV-SVPWM控制策略的三相Vienna整流器有着良好的运行性能,对直流侧电压波动有着更强的抑制能力。Aiming at the defects of three-phase Vienna rectifier controlled by fixed basic space vector spacer-space vector pulse width modulation in suppressing DC side voltage fluctuation, a variable basic space vector-space vector pulse width modulation(VBSV-SVPWM) control was proposed. The real-time voltage on the DC side was fed back to the control circuit to form VBSV-SVPWM control, which made the system had better response performance to the voltage fluctuation on the DC side. The simulation model was built in MATLAB/Simulink to verify the correctness of the theory. The experimental results show that the three-phase Vienna rectifier with VBSV-SVPWM control strategy has good operation performance and stronger suppression ability to DC side voltage fluctuation.
