摘要
在并联型有源电力滤波器(APF)中,直流侧电压的稳定对APF的性能起着非常重要的作用。针对并联型APF直流侧电压传统控制方法的不足,将改进的趋近率滑模控制运用于三电平并联型APF的直流侧电压的控制中。仿真和实验结果表明,该滑模控制器有效地提高了直流侧电压控制的鲁棒性,对三电平并联型APF直流侧电压控制技术实用化具有很高的价值。
For the shunt active power filter （APF）,the stability of DC-link voltage plays a very important role in its performance.Considering the shortcomings of traditional DC-link voltage control method for APF,an improved reach- ing law sliding mode control strategy is proposed and applied in three-level APF for DC-link voltage control.The simulation and experimental results show that the proposed method effectively improves the robustness of the DC-link voltage control and has high practical value for the DC-link voltage control in three-level APF.
