A novel hybrid APF is proposed, which can be adopted in high voltage system. The topology structure of the compensated system is given firstly. Its filtering principle is analyzed. Different controlling strategies are presented to select the right one for the compensated system. According to the selected strategy, the harmonic suppressing function is used to analyze the influence of system parameters on the compensated system with Matlab. Meanwhile parameters in injection branch is designed and analyzed. The harmonic suppressing and reactive power compensating performance are simulated with PSim. The experimental equipment was constructed in lab, which was used to improve the compensated system valid. The compensated system has good harmonic suppression and reactive power compensation through the analysis and real experiments. The system runs credibility.
