Active harmonic filtering one-stop solution for power quality management harmonic filtering, reactive power compensation, load balancing

Active harmonic filter is connected in parallel with non-linear loads, and uses one set of CT to detect the load current. It calculates each order harmonic current by FFT algorithms in its DSP microchips, and then generates a compensating current with the same amplitude but opposite phase angles to the detected harmonic current, which cancels out the original load harmonics.Not only eliminates harmonic current from the load side, but it also mitigates harmonic voltage caused by harmonic currents. The AHF system can also improve power factor (PF) and correct load imbalances in the power system.

Active Harmonic Filter AHF

YTPQC-AHF based on 3-level topology, is an Active Harmonic Filter (AHF) system designed to eliminate harmonic oscillations and reduce costs consequently. AHF is a versatile solution, easily tailored to deliver power factor improvement, voltage variation control, flicker mitigation and load balancing functionality, and highly improved power quality in networks while reducing harmonic pollution.
