1. 480/690V Industrial Active Harmonic Filter AHF Overview

Enjoypowers’ 480/690V industrial active harmonic filter AHF, use strong IGBT, provide high protection level for IGBT, and is applied to the harsh environment to mitigate power quality like power harmonics filtering, power factor correction, three-phase load balancing, effectively reducing line loss, and prolonging the service life of power equipment.
Enjoypowers’ 480/690V Industrial Active Harmonic Filter AHF is designed to suit very harsh application environments such as charged dust installations.
It is the power quality solution of choice for all power consumers, system integrators, and OEMs in harsh application scenarios.

2. Active Harmonic Filter Operating principle

Enjoypowers’ AHF is connected in parallel with the nonlinear load and uses a set of current transformers (CT) to detect the load current. It calculates each order harmonic current through the FFT algorithm in its DSP chip, and then generates a compensation current with the same amplitude but opposite phase angle to the detected harmonic current, so as to offset the original load harmonic.
