Analysis Of The Operating Principle Of Harmonic Filters And Harmonic Content Control

By optimizing the filter network parameters and selecting a suitable filter topology, the active harmonic filter cost can significantly suppress the harmonic frequency components in the system, ultimately achieving operation with extremely low harmonic content. This requires compliance with industry standards such as IEEE 519.

Based on passive or active technology architectures, the ahf harmonic filter can, under certain configurations, reduce the total harmonic distortion of the supply-side current to within the standard range. The passive automatic harmonic filter mainly uses a combination of LC inductors and capacitors to form a low-pass or resonant filter network to selectively block specific subharmonics. The active harmonic filter cost dynamically processes the harmonic components introduced by the nonlinear load through real-time detection and compensation, and corrects the waveform of the entire system.
