摘要

为了抑制网侧电流低次谐波，首先对其产生机理及分布规律进行了推导，并在此基础上给出了基于N 次陷波滤波器以及带谐波补偿的比例谐振控制器的电压电流双闭环谐波抑制算法。基于N 次陷波滤波器的电压外环控制能有效滤除直流侧电压的纹波而不影响控制系统的动态性能；基于谐波补偿比例谐振控制的电流内环控制能实现对交流信号的无稳态误差控制，并能有效抑制网侧电流的3、5、7 次等低次谐波。最后分别基于Matlab 仿真软件和dSPACE+TMS320F2812 半实物实验平台进行了仿真和试验验证，结果均验证了本控制算法的正确性

Abstract

For suppressing net-side low-order harmonics current, the mechanism and distribution of the harmonics were first derived. On the basis of theoretical analysis, a double closed loop harmonic suppression algorithms which combined N times notch filter and proportional-resonant (PR) controller was presented. The outer voltage loop control scheme based on N times notch filter can eliminate the DC-link voltage ripples without affecting the dynamic performance of the control system. The inner current loop control scheme based on PR controller with harmonic compensation can eliminate the steady-state error of AC signal, and further suppress the low-order harmonics in the line current, such as 3rd, 5th and 7th. Finally, the validity and effectiveness of the proposed scheme were verified with Matlab simulation and dSPACE+TMS320F2812 Hardware-in-the-Loop experiment results.
