Abstract :
Fluctuations and ripples in voltage or current of DC power systems cause different malfunctions in operation of equipments and systems which are supplied by low quality distribution power systems. Therefore ripple reduction of voltage or current in DC power systems is very important. In this paper a new method is proposed to reduce ripple of DC voltage in high power system using an active power noise cancellation filter (APNCF). In the proposed method a hybrid system including series and parallel active filters for ripple reduction of load voltage and source current is used. Simulation and experimental results show the performance of the proposed method in dynamic and static states.
