Introduction
SFR-APF series active power filter cabinet is a new type of power electronic device used to dynamically filter harmonics. It can filter harmonics (both magnitude and frequency change) in real time to overcome the shortcomings of harmonic suppression and reactive power compensation of traditional filters, realize the harmonic filtering function and reactive power compensation function of the system, and is widely used in electric power, metallurgy, petroleum, port, chemical industry, mining enterprises, etc. This series has independent intellectual property rights.
