ACTIVE HARMONIC FILTER / STATIC VAR GENERATOR

The active power filter (APF) is mainly composed of controller, isolation switch (circuit breaker), contactor, IGBT, driving circuit, protection system, fuse, connection reactor, DC capacitor, etc. The controller measures phase A, C reactive power(current), produces control signal, drives IGBT on/off and produces harmonic and reactive current same as system harmonic current but in an opposite phase to filter system harmonic, reduce reactive power and keep system power factor approximately at 1.

Our APF equipment is module structure, there are two types: Wall Mounted and cabinet mounted. The Wall Mounted type is preferred to be used in equipment improvement which is very convenient to install. The Sanhe Modular Active Harmonic Filter series are suitable for applications of all types, providing harmonic mitigation, load balancing and step-less reactive power compensation for inductive and capacitor loads.

Advantages

  • Optimize your harmonic filtering efficiency: the 3-Level Topology Design Approach

    Active harmonic filters analyze the line current harmonics and generate a compensation current at the opposite phase angle, "neutralizing" them. Attenuation > 97%.

  • Compact high performance

    Ultra-compact and space economical. User-friendly and easy to commission. Available in rack, wall mounting, and complete enclosure designs.

  • Enhanced Reliability Levels

    Incorporates intelligent FFT calculation for real-time sensing of network impedance, ensuring system stability. Advanced control algorithm for resonance protection.

  • Unique modular design

    Each module works independently, simplifying logistics, installation, and maintenance. Modular power ratings from 35A to 150A with unlimited parallel combination. Maximum capacity per cabinet can be 600A.
