Active Harmonics Filter

Active harmonic filters are parallel filters (which means the current doesn’t go through the filter) that are used to reduce, or mitigate, harmonics to tolerable levels as defined by IEEE-519. Active filters use a set of transistors and capacitors to filter (or clean) the current wave by injecting inverse currents to cancel out the undesired harmonic components. Active filters are significantly more expensive than passive filters and take up more space. Size is an immense factor in system design today and should be accounted for when deciding on what type of harmonic filter is right for you.

Our AHF’s use IGBT fired circuits to mitigate harmonic distortions within the load or the network of hundreds wherever they’re put in. Our AHF series is a sophisticated standard Active Harmonic Filter (AHF) system. The AHF system is made of one or many filter modules with system controller.
