1.Product Description
The APF Active Power Filters 3P4W is mainly applied with 4 wire system,it’s IGBT based 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,APF Active Power Filters 3P4W can also improve power factor (PF) and correct load imbalances in the power system.

5.Working Principle
External CT detects the load current, DSP tracksinstruction current and calculates the reactive power change rate through the Instantaneous Reactive Power Algorithm. Then DSP sends PWM signal to IGBT driving board which can control IGBT on and off to generate the same amplitude reverse compensation current. At the same time CT detects the output current and compensation result is fed back to DSP, then the next round of logic control is carried out to realize stable power grid.
