Harmonic Filters & Sizing Analysis

??

Harmonic filters are extensively used to mitigate harmonic problems.

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 Filters & Sizing Software Key Features

Harmonic Filter design and sizing of multiple filter types based on IEEE Std. 1531-2020
Harmonic filter sizing based on power factor correction, minimum cost, or minimum operation objective
Automatic harmonic filter overloading checking & alert
Preview filter behavior by plotting existing and newly sized filter impedances vs. the harmonic order

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 (Notch)
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

The integration of electric vehicles (EVs), PV systems, battery energy storage systems (BESS), and more has presented us with exciting opportunities and challenges. One such challenge is the need for unbalanced network harmonic analysis, especially when dealing with single-phase charging vehicles and inverter controls.
