APF possesses unprecedented comprehensive electric energy quality governance capacity and is capable of simultaneously eliminating harmonic within 2-50 orders. The filtering capacity can reach as high as 97% and above. The complete compensation time of harmonic with step change is less than 10ms. Parallel operation of multiple APFs can be realized simultaneously with the efficiency of overall unit exceeding 97.5%. APF is completely suitable for handling various conditions in industrial and civil fields. It is the best solution for nonlinear load harmonic suppression and reactive compensation.
