Active power filter (HZ-APF)

Product manual

The main circuit of HZ-APF series active power filter is IGBT power converter, detection technology based on instantaneous reactive power theory,automatic tracking of harmonic changes in the grid, Highly controllable and fast responsive. Overcoming the shortcomings of the traditional passive filter, such as poor filtering effect, easy resonance, and only compensation for fixed subharmonics, good filtering and compensation for shock loads of various fast transients.

HZ-APF series active filter adopts military-grade control chip, extremely powerful in computing and anti-interference,can realize one controller to centrally control multiple active filters to work in parallel, adaptive current average control algorithm combined with LCL topology, overcoming the shortcomings of traditional hysteresis current control due to switching frequency variation, wide output spectrum range, difficult filtering, high frequency harmonics will interfere with the power grid, etc..
