AHF
Active Harmonic Filters (AHF) covering 208V to 800V, with efficiency up to 99%. An AHF is a real-time, IGBT-based or Sic-based active filter that detects harmonic currents drawn by non-linear loads and injects equal, opposite currents to cancel them at the source — restoring a clean sinusoidal waveform and correcting power factor. Used across industrial plants, commercial buildings, data centers, hospitals, EV charging and renewable sites where harmonic distortion, PF penalties or grid instability are a concern.
Active Harmonic Filter Series →SVG
CHITEK Static Var Generator (SVG) employs advanced IGBT or Sic switching at up to 25.6kHz to precisely regulate inverter voltage magnitude and phase. An SVG is a real-time reactive power compensator that injects or absorbs reactive current to dynamically correct power factor and stabilize voltage — eliminating penalties, sag and flicker. Used across industrial plants, commercial buildings, data centers, renewable farms, EV charging hubs and utility networks where reactive power, voltage fluctuation or load imbalance are a concern.
