APF - Active Power Filter

Dynamically filters grid harmonics, suppresses resonance, and improves power quality through real-time detection and generation of reverse harmonic current.

Get in touch→

Core Function: Primarily harmonic filtering. It uses external current transformers to detect harmonic currents in the power grid in real time and actively generates a compensation current of equal magnitude and opposite phase to cancel out the harmonics.
Additional Functions: Capable of providing minor reactive power compensation and correcting three-phase unbalance.
Technical Features: Employs fully controlled technology, enabling precise mitigation of harmonics ranging from the 2nd to the 50th order.
