Enhance Power Quality | Infineon IGBT Inside | Dual Functionality Available | Eliminate Harmonics | Improve Efficiency
Our Active Harmonic Filter (AHF) is a high-performance solution engineered to tackle harmonic distortion, poor power factor, and load imbalance with unmatched precision. Powered by Infineon IGBTs, known globally for their reliability and efficiency. Our AHFs are ideal for industrial and commercial facilities, AHFs ensure compliance with IEEE 519 and other international power quality standards, protecting sensitive equipment and improving overall energy efficiency.
APF (Active Power Filter) – Focuses on harmonic elimination, load balancing, and dynamic power factor correction.
APF + SVG (Hybrid Model) – Combines harmonic filtering with Static Var Generation for advanced reactive power compensation and voltage stability.
Whether you need a compact solution for harmonic distortion or a full-spectrum system for complete power conditioning, our AHF range offers a perfect fit.
