Abstract |
In this brief, we propose a novel filter to eliminate undesirable harmonic from composite signal using RLS algorithm. The proposed approach eliminates all harmonics component from selected variable (current or voltage) and it requires only knowledge of the frequency of the fundamental component. Using frequency of fundamental component of composite signal, the outputs of the adaptive filter is a harmonics replica and is subtracted from the original composite waveform to eliminate them. The bipolar waveforms are roughly analyzed and considered case of square wave pattern which contain all odd harmonics. The simulation results show that the method can effectively eliminate undesirable harmonics and sine wave is produced. |
