摘　　要：现有的有源滤波器多采用开环控制算法,其谐波补偿性能受参数不确定和干扰的影响较大。详细论述了并联型有源电力滤波器(Active Power Filters,简称APF)直流侧电压的控制策略和补偿电流的跟踪控制,采用TMS320LF2407 DSP完成了并联型APF系统的硬件和软件设计。试验结果验证了提出的并联型APF控制策略的正确性和有效性。Open-loop control strategies are widely used in Active Power Filters （APF） these years,while the performance would be influenced heavily by disturbances as well as parameter uncertainty.The Shunt APF＇s control strategy including DC voltage control is introduced and compensatory＂ current control is analyzed in detail.The shunt APF system＇s hardware and software design was implemented with TMS320LF2407 DSP.The experiment results verify the validity and effectiveness of the current detection method and the control strategy.
