Active Harmonic Filters: The Future of Power Quality

Inventum Power Private Limited

In today's fast-paced world, electricity has become an indispensable commodity. We rely on it to power our homes, businesses, and even our vehicles. However, the quality of electricity is often compromised due to the presence of harmonic distortions. These distortions can cause a range of issues, from poor power factors to equipment damage. That's where Active harmonic filters come in. At Inventum Power Private Limited, we specialize in these cutting-edge products, and in this article, we'll tell you everything you need to know.

What are Active Harmonic Filters?

Active harmonic filters (AHFs) are advanced electronic devices that mitigate harmonic distortions in power systems. They use sophisticated algorithms to detect, analyze, and eliminate harmonic currents and voltages in real time, ensuring a clean and reliable power supply. AHFs are installed in parallel with the load or the source, depending on the application, and can handle both linear and nonlinear loads.

How do Active Harmonic Filters Work?

AHFs work by injecting compensating currents into the power system that cancel out the harmonic currents generated by nonlinear loads. They use pulse-width modulation (PWM) technology to generate compensating currents synchronized with the harmonic currents. The result is a clean and sinusoidal waveform that meets the stringent power quality standards set by regulatory bodies.

Benefits of Active Harmonic Filters
The benefits of AHFs are numerous and significant. Here are just a few:
  • Improved Power Quality:- AHFs improve power quality by reducing harmonic distortions, improving power factor, and eliminating voltage fluctuations. This leads to better equipment performance, reduced downtime, and fewer maintenance costs.

  • Energy Efficiency:- By improving power quality, AHFs can also increase energy efficiency. They reduce the amount of reactive power consumed by the load, which can result in lower electricity bills and a smaller carbon footprint.


  • Compliance with Standards:- AHFs ensure compliance with a range of international standards, such as IEEE 519, IEC 61000, and EN 61000. This is particularly important for industries that have strict power quality requirements, such as data centers, hospitals, and manufacturing plants.


  • Longevity of Equipment:- By reducing harmonic distortions, AHFs can extend the lifespan of equipment, including motors, transformers, and cables. This means fewer replacements and upgrades, resulting in significant cost savings.

Applications of Active Harmonic Filters

AHFs can be used in a wide range of applications, from commercial buildings to industrial facilities. Here are some examples:

  • Data Centers:- Data centers rely on clean and reliable power to operate their servers, storage devices, and networking equipment. AHFs ensure that the power supplied to these critical components is free from harmonic distortions and voltage fluctuations.

  • Manufacturing Plants:- Manufacturing plants often have a mix of linear and nonlinear loads, which can generate harmonic currents that affect the performance of equipment. AHFs can mitigate these distortions, ensuring optimal operation and reduced downtime.

  • Hospitals:- Hospitals require a stable and clean power supply to operate their life-saving equipment, such as ventilators, heart monitors, and MRI machines. AHFs can ensure that the power supplied to these devices is free from harmonic distortions and voltage fluctuations, reducing the risk of equipment failure and patient harm.
