اَلْعَرَبِيَّةُ Active power filters use power electronics technology to detect harmonics in real time and generate compensating currents of equal magnitude but opposite direction to cancel out the harmonics.
Advantages
- Strong dynamic compensation capability
- Filtering effect can reach over 90%
Disadvantages
- Higher cost
- Capacity limited by power devices
- More suitable for small to medium power applications
