Automatic Harmonic Filter (AHF) - Instant Harmonic Mitigation

Reliable Harmonic Mitigation
The ValBrid Automatic Harmonic Filter (AHF) is engineered to mitigate harmonics directly at the source, reducing THDi/THDv and ensuring cleaner power quality. This protects motors, transformers, and cables from overheating while extending asset life and reducing maintenance costs.

Improved Power Factor and Compliance
By removing distortion currents, the AHF enhances true power factor and supports IEEE-519 compliance at the Point of Common Coupling (PCC). This helps facilities avoid costly penalties and audits while maintaining energy efficiency.

Advanced Control and Flexibility
The system uses IGBT-based shunt filtering with fast response loops to inject equal-and-opposite currents, effectively cancelling targeted harmonic orders. Selective filtering options (e.g., 5th, 7th, 11th) adapt seamlessly to variable industrial loads.

Modular and Scalable Architecture
Designed with a modular, stackable structure, the AHF allows precise capacity matching today with easy expansion as demand grows. Intermediate current steps ensure optimal performance without over-sizing.

Industry Applications
Ideal for manufacturing facilities, steel production, data centers, and commercial buildings with fluctuating or heavy non-linear loads. Remote monitoring capabilities provide real-time insights into PF, THD, and system balance, supporting data-led commissioning and predictive maintenance.
