Active Harmonic Filter APF Reduce harmonic THDi<5% UL CE CSA

APF Introduction

Active harmonic filter (AHF) is a new active electronic harmonic filtering device to reduce voltage harmonic and current harominic and improve power quality.

Based on voltage source inverter, it's connected in parallel with non-linear loads which need to compensate.

For compensating harmonic current which is with changing Amp and frequency and reactive power, it overcomes the shortcomings of traditional passive filter. It has the advantages of high compensation accuracy and fast dynamic response etc.

Why Should APF and SVG?

Because of power quality problem exist, and cause many problems:

Power quality problem:

Waveform distortion because of harmonics


What is Harmonic? 

A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency.

i.e. if the fundamental frequency is 50Hz, the frequencies of the next harmonics are: 100 Hz (2nd harmonic), 150 Hz (3rd harmonic), 100 Hz (4th harmonic) etc.

                                    Harmonic

How APF beneficial to customers?

After Harmonic compensation

Improve equipments reliability, reduce economical loss caused by equipment false action.

Reduce line heating, reduce insulation aging, improve safety and reliability of electricity using.

Reduce resonance probability of compensation capacitor, improve the safety of the electricity using.

Reduce electromagnetic interference produced by harmonic, ensure communication system normal operation.

Meet national standard requirements.
