摘　　要：阐述了并联型电力有源滤波器(SAPF)启动时变流器直流侧电压、电流过冲的问题及其危害,并提出了采用PI控制器控制变流器直流侧电压软启动的解决方案,最大限度地降低装置启动瞬间的冲击电压、电流。文章给出了相应的理论分析和仿真结果,并根据仿真结果进行了试验。试验证明采取该方法能有效地降低APF装置启动时变流器直流侧的电压、电流冲击,确保了APF装置在系统中长期安全运行的可靠性。The problem which is caused by the over impact of the DC side voltage and current in shunt active power filter is presented. The mild start-up of DC side voltage based on digital PI （Proportional and Integral） makes the problem solved. Here, the theoretical analysis and simulation results of the proposed method are given in details. The results from simulation and tests verify the feasibility and effectiveness of the proposed method.
