针对T型三电平整流器,提出一种快速预测控制和矢量调制方法.当直流侧负载出现扰动时,和传统PI控制方法相比,预测控制能够实现直流侧电压的快速跟踪.并网控制方面,和传统方法相比,不需要调节参数和具有快速的动态响应.针对T型三电平整流器存在的中点电位振荡问题,提出一种新型调制方法,该方法内容能够给实现中点电位振荡和偏移抑制.最后通过仿真验证了所提出的控制以及调制正确性.“,”A fast predictive control and vector modulation method for T three-level rectifier is proposed in this paper. When the DC side load is disturbed, compared with the traditional PI control method, the predictive control can achieve fast tracking of the DC side voltage. Compared with the traditional methods, the grid connected control system does not need to adjust the parameters and has fast dynamic response. For neutral point potential oscillation problems of T type three-level rectifier, this paper proposes a new modulation method, this method can realize the content to the neutral point potential oscillation and migration inhibition. Finally, the correctness of the proposed control and modulation is verified by simulation.
