摘　　要：针对VIENNA整流器三相电流的基波分量和奇次(2k+1)谐波分量建立旋转坐标系下的数学模型,其中基波分量转换成为直流量,(2k+1)次谐波分量转化为2k次交流量。根据数学模型设计基波和奇次谐波分量的复合控制策略,提出了三相VIENNA整流器的快速重复控制策略,并采用MATLAB进行仿真验证。理论分析和仿真结果表明,快速重复控制策略减少了重复环节的数据运算量和存储量,提高了输入电流的动态响应速度。Amathematical model of the three-phase current of Vienna rectifier in the rotating coordinate system is established according to the fundamental component and the odd(2k+1)harmonic component,in which the fundamental component is converted into the direct flow,and the(2k+1)harmonic component is converted into the 2k AC flow.According to the mathematical model,the compound control strategy of fundamental and odd harmonic components is designed,and the fast repetitive control strategy of three-phase Vienna rectifier is proposed,and is verified by MATLAB simulation.Theoretical analysis and simulation results show that the fast repetitive control strategy reduces the amount of data calculation and storage in the repetitive link,and improves the dynamic response speed of the input current.
