Active power filter

Active power filters ( APF) are filters, which can perform the job of harmonic elimination. Active power filters can be used to filter out harmonics in the power system which are significantly below the switching frequency of the filter. The active power filters are used to filter out both higher and lower order harmonics in the power system. [1]

Harmonic filtering

Operating principle. An LC circuit, tuned to each harmonic order to be filtered, is installed in parallel with the non-linear load (see Fig. M28 ). This bypass circuit absorbs the harmonics, thus avoiding their flow in the distribution network. Generally speaking, the passive filter is tuned to a harmonic order close to the order to be eliminated.
