Active Harmonic Filters – TDD Control

IPU SA’s Active Harmonic Filters (AHFs) are advanced solutions designed to reduce Total Demand Distortion (TDD)to below 5%, improving power quality, equipment lifespan, and overall system efficiency. These filters work in real-time by detecting harmonic currents and injecting opposing waveforms to neutralize distortion at the source.

Built to meet IEEE 519 standards, AHFs are essential for facilities with nonlinear loads such as VFDs, UPSs, and data center infrastructure.
