Product Introduction
The active power filter (APF) mainly consists of an IGBT power converter. Using detection technology based on the instantaneous reactive power theory, it automatically tracks the harmonic changes in the power grid, featuring high controllability and fast responsiveness. It overcomes the shortcomings of traditional passive filters, such as poor filtering effect, easy resonance, and the ability to only compensate for fixed-order harmonics, and can effectively filter and compensate for various fast-transient impact loads.
