Product Overview
The working principle of an active harmonic flter is to detect the load current in real time.Based on a specified sub harmonic current detection algorithm,the harmonic current is gradually separated,and a control signal is generated according to the set fltering percentage to drive the IGBT to output a compensation current with the same amplitude and opposite phase as the load harmonic current,achieving the purpose of harmonic cancellation.
