Operating Principle:

• Measure the harmonics current generated from the non-linear load.
• Generate opposite phase shifted harmonics current of the same amplitude.
• Cancel the loads harmonic current and then obtain a sinusoidal current in the utility.

Benefits of Active Power Filter:

• No risk of harmonic resonance
• Significantly reduce the voltage waveform distortion
• Reduce voltages drop on transformers & cables
• Reduce temperatures rise on transformers & cables
• Improve power factor
