Harmonic Filters & Sizing

Harmonic Filters & Sizing Analysis

Harmonic filters are extensively used to mitigate harmonic problems.
System Harmonic Waveform
A properly designed harmonic filter can prevent the harmonic current from injecting into the system, or it can provide a low impedance path at the tuned frequency to remove a parallel resonance. The Harmonic Filter editor provides all the practical and popular filter structures for you to choose from.

Harmonic-Filter-Sizing

Built-in Harmonic Filter Types

  • By-Pass

    By-pass frequency characteristic

  • High-Pass Damped
    High-pass with damped frequency characteristic

  • High-Pass Undamped
    High-pass with undamped frequency characteristic

  • Single-Tuned
    Single-tuned frequency point

  • 3rd Order Damped
    Special high-pass damped filter where the inductance is replaced with a series LC Circuit to provide zero losses at the fundamental frequency and therefore avoiding parallel resonance

  • 3rd Order C-Type
    Special high-pass undamped filter where the inductance is replaced with a series LC Circuit to provide zero losses at the fundamental frequency and therefore avoiding parallel resonance
