Product Overview
The working principle of AHF 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 filtering 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 compensation function.
