As per grid harmonic current and voltage control requirements, automatically output compensation current and effectively filter system's 2-50 times harmonic, filter rate>90%;
According to user load characteristics, randomly select three working modes below: only eliminate harmonic current, meanwhile eliminate harmonic current and reactive compensation current, only compensating reactive current;
Intelligent judging, optimal control, quick response and fully realize stageless compensation; dynamic response speed in 5ms; fully compensate dynamic load in 10ms;
Compared with LC passive filter, it's subject to little influence from the grid impedance; the possibility of parallel resonance between filter and grid impedance is eliminated;
Up to 5 APF active power filter can be used together in parallel.
