BY91 Series Active Power Filter

Power Solution for modern Power Distribution Systems! The BY91 Series Active Harmonic Filter (APF) is a cutting-edge Active Harmonic Filter Design engineered to eliminate harmonics, correct power factor, and stabilize voltage fluctuations in industrial and commercial Electric Power Distribution networks. Utilizing IGBT-based power conversion and adaptive current control algorithms, it dynamically suppresses 2nd–50th order harmonics with >97% efficacy, reducing THDi to <5% and ensuring compliance with global Power Quality standards. Unlike Passive Harmonic Filters, which risk resonance and fixed-band compensation, our Shunt Active Power Filter offers real-time response, resonance damping, and multi-functionality—addressing harmonics, reactive power, and load imbalance in a single Power Tech Solutions platform.

    Product details

    The BY91-APF active power filter can effectively monitor harmonics and extract harmonic currents from them. The device emits inverse harmonic currents through GBT, completely suppressing harmonics at the device connection point, and avoiding greater losses caused by harmonics flowing into circuit breakers or transformers. At the same time, the device can also manage reactive power and three-phase imbalance phenomena, truly achieving intelligent integrated power quality management.BYAPF can effectively filter out 2-50 harmonics.
