摘要
对用于一种特殊的高精度、低纹波直流电源的直流有源滤波器的主电路结构和抑制纹波的基本原理进行了分析 ,提出了两种控制方法 ,并在此基础上研制出了实验装置。结果表明 ,由无源滤波器和有源滤波器构成的混合滤波器能大大降低电流纹波和提高电源的稳定精度。一台实际的工业装置测试表明 ,其纹波达到了 10ppm。
The main circuit configuration of DC active power filter used in a DC power supply and its basic concept for suppression harmonics are analyzed,and two kinds control strategy are presented On the basis of these a experimental device is developed The results show that the hybrid filter consisting of passive filter and active filter can improve the performance of high precision,low ripple and fast response Tested by a practical device,its ripple achieves 10ppm
