YTPQC-AHF Active Harmonic Filter can realize 2nd to 50th harmonic compensation with full compensation or seletive compensaton, output compensation current follows the system harmonic variation, devoted to green power quality. Our AHF's compensation capacity(ratio) can be set freely by the customers, to realize harmonics compensation, reactive power compensation or imbalance compensation.
YTPQC-AHF Acitve Filter avoid resonance
Our AHF detects the resonance point, stops compensating at this point to avoid amplify resonance, realizing the system protection. The main principle is our AHF adapts two sets of current transformer + passive damping + adaptive algorithm which can effectively avoid resonance.
