摘　　要：为降低三相三开关三电平VIENNA整流器的开关损耗,在分析整流器模型并讨论其调制技术和控制的基础上,提出了VIENNA整流器断续调制技术。该方法通过减少整流器最大电流相的开关次数,从而提高系统效率。为了进一步平衡中点电位、有效抑制中点电位的波动,在断续调制的基础上继而给出了一种针对角度的控制策略,并给出对应的调制方法以及控制器,最后通过仿真和实验对结论进行了验证。To reduce the switching loss of three-phase three-switch three-level VIENNA rectifier,on the basis of analyzing the rectifier model and discussing its modulation technology and control,the intermittent modulation technology of VIENNA rectifier was proposed. This method improves the system efficiency by reducing the switching times of the maximum current phase of the rectifier. In order to further balance the midpoint potential and effectively suppress the fluctuation of the midpoint potential,on the basis of intermittent modulation,a control strategy for angle was given,and the corresponding modulation method and controller were given. Finally,the conclusion was verified by simulation and experiment.
