ARK AHF Active Harmonic Filters Boosting Power Quality in Industrial Systems

ARK AHF Active Harmonic Filters - Enhance Power Quality for Industrial Systems

Product Overview

ARK AHF Active Harmonic Filters are the ultimate solution to power quality problems caused by waveform distortions, low power factor, voltage variations, voltage fluctuations, and load unbalance. They are high-performance, compact, flexible, modular, and cost-effective active power filters (APF) that provide an instantaneous and effective response to power quality issues in low or high voltage electric power systems.

The AHF working principle involves external CT detecting the load current. DSP as CPU has advanced logic control arithmetic, which can quickly track the instruction current, divide the load current into active power and reactive power using intelligent FFT, and calculate the harmonic content rapidly and accurately. Then it sends PWM signals to internal IGBT's driver board to control IGBT on and off at 20KHZ frequency. Finally, it generates opposite phase compensation current on the inverter induction. Meanwhile, the CT also detects the output current and provides negative feedback to the DSP. Then the DSP proceeds with the next logical control to achieve a more accurate and stable system.
