摘要
阐述了并联有源电力滤波器在启动过程中直流侧电压和电流过冲的问题,提出了一种改进的软启动控制策略,并将其与传统的PI控制方法相结合,有效降低了启动瞬间的冲击电压和冲击电流.在电源电流直接控制方法的基础上,阐述了负载动态情况时的直流侧电压的控制问题,并用仿真软件MATLAB/Simulink进行仿真验证,结果证明了该方法理论上的正确性.
The issue of over voltage and over current which occurs while the active power filter（APF）is started is briefly described.And integrated with traditional PI control method,a developed control strategy is presented here.The proposed control strategy does suppress the over voltage and over current.The simulative result by MATLAB/Simulink demonstrates the validity of the method proposed above.
