Current harmonic filter is a unit connected in parallel with the load at the load itself which injects the total harmonic current demanded by the load, and thus preventing harmonic
There are two types of harmonic filters like active and passive. The major difference between these two is the components used while designing the filter. The active harmonic filter uses active components like ICs, BJTs, IGBTs & MOSFETs whereas the passive harmonic filter uses different passive components like resistors, capacitors, and inductors.
Part of PowerLogic™. AccuSine PCS+ by Schneider Electric is an advanced Active Harmonic Filter (AHF) that enhances power quality in electrical networks. It identifies and mitigates harmonics, improving power quality significantly. Unlike passive filters, AccuSine PCS+ dynamically adapts to varying harmonics, making it highly effective.
Active filters: Active harmonic filters inject compensating currents into the system to neutralize harmonic currents generated by solar PV inverters, such as inverters.

These harmonic components obtained is filtered with the designed filter structure and the effects of the filter structure at each filtering degree on the harmonic components and THD were investigated. In this way, the designed filter is proved to be an adaptive model that can be adjusted automatically for different types of LED systems.</br>
Active Harmonic Filters – Also known as active harmonic conditioners, these filters are often used in commercial installations with loads less than 500kVA. They help to reduce current distortion that could lead to equipment heating and circuit overloads.
The harmonic filters use a compact design and flexible mounting concept. Because the capacitor bank can be mounted separately from the core – up to 2 meters apart, a machine builder can easily position and mount the components inside an enclosure. As an option, we offer large filters in a pre-wired NEMA1 enclosure.
These filters are IGBT-based power converters. This filter injects negative of the harmonic current resulting in practically no harmonic distortion. Phase balancing and power factor correction is also achieved. Features: 30-600 A Active filter in 3 phase 3 wire/4wire; Stand-alone & modular units; Response time less than 1 ms

A series tuned harmonic filter is a combination of inductor and capacitor designed to trap a certain harmonic. These filters are applied in parallel with the power system and is often called shunt passive filters. For most harmonic filters in power systems, filters are tuned to 4.2 or 4.7 for trapping 5th order harmonics.
