In this paper the topology and principle of APF for stable DC power supply are analyzed in detail. Then the model of the whole power system has been established. Based on it, several parameters which influence the system quality are studied, especially for the APF and the coupling transformer. Finally, the simulative and experimental results of the system are presented. The output voltage and current of stable DC power supply are possessed of low ripple and high stabilization. Thus the correctness and effectiveness of APF are verified.
