Research and Design of Aviation Active Power Filter Based on DSP

As the application of power electronic devices in aviation power system become more and more widely, the harmonic and reactive power problems are becoming more and more serious. Active power filter has become an important research direction of power electronics technology. In this paper, the harmonic harm and harmonic suppression methods are briefly described. Then the software and hardware of APF are designed. Finally, the system is simulated by Simulink, which proves the rapidity and accuracy of harmonic and reactive current detection and compensation.
