Active Harmonic Filters provide reduction of system harmonics as well as highly dynamic reactive power compensation. Connected in parallel with the harmonic-generating loads, the Active Filter analyses the system harmonics profile and "injects" a counter-phase harmonic compensation current into the network, i.e. neutralising the
Besides passive filters, more and more active harmonic filters are now used, especially where the PF is close to 1 and harmonic disturbances change frequently. EPCOS PQSine active harmonic filters and power optimizers help to eliminate harmonic pollution from the grid, reduce power quality problems and use energy more efficiently and reliably.
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

In simple terms, an active harmonic filter is a device designed to mitigate harmonic distortions in an electrical system. These distortions, caused by nonlinear loads such as variable frequency drives, computers, and LED lighting, can lead to voltage fluctuations, increased losses, and overheating of equipment.
Active filters are used for harmonic elimination in power systems. Unlike passive filters that use reactive power components (capacitors and inductors) to create a path for harmonic currents, active filters work by injecting currents that are equal in magnitude but opposite in phase to the harmonic currents present in the system.

An Active Harmonic Filter (AHF) provides an effective means to mitigate harmonics, reduce process-related voltage fluctuations and improve equipment operating life and system capacity. It can be part of a power factor correction and harmonic filtering system.
PQSine S-Series monitors the current signal and compensates the unwanted elements of the measured current. In this way, the filter ensures harmonic suppression independently of the number of loads. Ideally, PQSine can be used in hybrid solutions, for example, with a 7% detuned PFC (power factor correction) system to achieve the best results

Filter circuits can absorb more harmonic currents. Harmonic filters in action when the harmonic levels are too high (on photo: Merus Active Harmonic Filter (Open); credit: RWW ENGINEERING) This means that, like reactor-protected systems, they consist of one series circuit of reactance and a capacitor.
