摘要
介绍了一种高精度、低纹波稳定电源用直流有源滤波器的工作原理和控制方法 ,在此基础上研制了实验装置。实验结果表明 ,由无源滤波器和有源滤波器构成的混合型滤波器能大大降低稳定电源的电流纹波和提高电源的稳定性。一台实际的工业装置测试表明 ,其纹波能达到 10ppm。
The basic concept and control strategy of DC active power filter used in a high precision and low ripple power supply are presented in this paper, and an experimental device is developed. The results show that the hybrid filter consisting of passive filter and active filter can reduce current ripple enormously and improve the stability of the power supply.Measurement on a practical device shown that its ripple achieves 10ppm.
