Why Active Harmonic Filters Are So Effective At Mitigating Harmonics?

Active harmonic filters are one of the most effective solutions to countering harmonic distortion. But what makes them so effective as a harmonic filter? In this blog, the mechanism of active harmonic filters is explored, along with some of its major benefits.

How Active Harmonic Filters Work?

To understand the workings of an active harmonic filter, it is best to use an analogy. In this case, it is a noise-cancelling headphones. Just like headphones listen to the incoming sound waves and send out a frequency that is completely out of phase to them, active harmonic filters also function in a similar fashion.

These harmonic filters have a digital signal processor (DSP), that is used to calculate the harmonics within a system with the aid of Fourier transform. It then sends out a frequency that is 180 out of phase with the incoming harmonics, ensuring smooth harmonic mitigation.

Benefits Of Active Harmonic Filters

Such a comprehensive system provides a few major benefits:

Adaptability

Active harmonic filters are a flexible and versatile power quality solution. This means they can handle multiple frequencies from multiple sources, unlike more conventional power quality solutions such as passive harmonic filters, which can only mitigate fixed frequencies.

Improved Power Quality

By effectively removing harmonic distortion, active harmonic filters improve the power quality of a particular system. This means that the equipment will use the input current more effectively and not generate a lot of reactive power, making the entire process more cost-effective.

Protecting Equipment From Damage

With the presence of a high level of distortion, equipment damage is a possibility as it causes overheating. Active harmonic filters can mitigate this by dealing with the harmonics, thereby protecting precious equipment from damage caused by overheating and other side effects of harmonics.
