What is an active power filter?
An Active Power Filter is a power electronics device used to address power quality issues, such as low power factor, as well as voltage and current harmonics, which are caused by the increasing use of nonlinear loads in electrical systems.

How does an active filter work?
Principles of Active Filtering
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.
