    AHFs are available in two variants for two performance levels: approximately 14 %, compared to 10 % at the nominal load of AHF005 with 5 % THiD (total current harmonic distortion) and 34 A. On the other hand, the total harmonic current is only AHF010 with 10 % THiD.

    20 and 25 %). The power factor increases with the load. Because of the higher value of the main inductor L0 Illustration 4.1: AHF005 in the AHF005, the power factor is slightly higher than in the AHF010. Following graphs show typical values for the true power factor on AHF010 and AHF005.

    In some cases this very dynamic compensation can produce resonances in the DC link and should then be disabled. Typical cases are where AHF005/010 is used on supply grids with high short circuit ratio. Fluctuations can often be recognized by increased acoustical noise and in extreme cases by unintended tripping.
